Many factors influence the humidity distribution of surrounding rock in roadway of swelling rock.
It is neither possible nor necessary to set all the factors in the simulation test alike .Selecting the appropriate conditions of similarity, developing the reaction of expansive rock physical and mechanical properties of similar material, is the key to correct simulation prototype.
But due to the numerous factors that affect the expansive characteristics of swelling rocks and the complexity of the geological condition, until now the material similar of swelling rock is still not suitable.
Since compared with other ratios, the properties of the similar material corresponding to ratio A is the closest to physical and mechanical property indexes required by material model test; (4)In future studies of the expansive rock similar material mixture ratio, in order to seek more ideal expansion rock similar material, the more in-depth investigation of mineral properties and shrinkage can be conducted.

In this paper, index system of the safety of VCM storage tanks was established by analyzing four main factors including 18 indexes, based on accidents statistic and technology experience.
There are many factors which will cause the leaking of VCM, such as mechanical effect (shock), chemical effect (corrosion), higher pressure and incorrect operation.
In order to assess the safety of VCM tanks more credibly, we used analytical hierarchy process (AHP)-fuzzy comprehensive evaluation method to evaluate the safety of VCM tanks, taking full account of the various factors affecting VCM tanks safety and combining the qualitative and quantitative analysis, so as to establish model for safety assessment of VCM tanks.
Establishment of Index System for the Safety of VCM Storage Tanks In view of the complexity of factors affecting the safety of VCM storage tanks and the independence of factors, the study is divided into three levels based on the statistical analysis of VCM leaking accident and the experience of personnel in charge of technology or safety.[2] Specific safety index system of VCM storage tank is shown in Fig. 1.
Level B is criteria that are operation factors, safety reliability of the tank, safety accessories, detection and protection of the tank.

Introduction Rock mass in-situ stress field is affected by several factors, among which the effect of the structural plane is quite significant and also quite difficult to precisely evaluate, using numerical method to analyze this problem is necessary and feasible.
Considering the complexity of the mechanical properties of the structural plane, it is generally simplified in numerical model, usually adopting rigid or linear deformation model[3,5], but the linear deformation model could not precisely reflect its actual physical and mechanical properties, several non-linear deformation structural plane have been proposed, among which the Barton-Bandis hyperbolic model is widely used[6,7].
Fig.7 shows the distribution of stress concentration factor of the maximum principal stress in the affected zone.
Actual structural plane deformation is non-linear, deformation stiffness is related to the physical and mechanical properties of the structural plane, and vary with the load, the BB hyperbolic model could well reflect the actual deformation process of the structural plane under load.

Low carbon steel shows the typical mechanical properties in tensile test, so this kind of steel is widely used in engineering applications [1].
Tensile test of metal material is a kind of test method used for determining mechanical properties of materials.
The performances of metal material such as elasticity, plasticity, strength and toughness under the external force are called the mechanical properties [2].
Because it hardly affected the material properties, the initial tensile curve was straight line.
It is less affected by external factors, so in general engineering applications modulus of elasticity is regarded as constant.

a hadyun@163.com, bbtwang@hhu.edu.cn Keywords: lime stabilized expansive soil, wet and dry cycle, direct shear test, consolidation test ABSTRACT: Lime Stabilized expansive soil is often used as filler in road subgrade, although many scholars have done a lot of research, the mechanical properties under wet and dry cycle role remains unclear.
Wetting and drying cycle caused by the variability of environmental conditions is the main factor lead to degradation of mechanical properties of embankment filler, the embankment filler loss water and shrink in the dry season, and bibulous saturated and inflation in the rainy season, so the role of the reciprocating will lead to the change of the structure of the soil, soil strength gradually reduced, which finally causes the destruction of roadbed.
Based on the above background, the article carry out test study on mechanical properties of the lime stabilized expansive soil under wet and dry cycle, to explore the strength variation and stability strength of lime stabilized expansive soil under wet and dry cycle.
CONCLUSIONS With all the above results, the mechanical properties of lime stabilized expansive soil under wet and dry cycle have such characteristics as follows:  The strength of soil will decrease especially in previous cycle, and the trends can be expressed with logarithmic model

Nickel based super alloy, Inconel 718 is an aerospace material and considered one of the most difficult-to-machine material which attributed to its ability to maintain hardness at elevated temperature, very poor thermal properties, high toughness, high hardness, and high work hardening rate and consequently it’s very useful for hot working environment.
Copper became the metallic electrode material of choice for EDM even though it wear rate is higher due to the melting point temperature of copper is low but copper have high in electrical and thermal conductivity properties.

Due to the station ring material of high modulus of elasticity, station ring deformation was mainly affected by temperature, and the temperature change was the same trend; and the elastic modulus of the material static ring was relatively smaller, the surface deformation in addition to affected by temperature, but also the force
In the process of loading, the parameters change rule by time adequately described the friction of mechanical face seal of thermal-mechanical effects, namely the friction heat will cause thermal deformation, thermal deformation caused by uneven contact and the contact area was reduced, thereby cause contact area to reduce and temperature rise.

The main factors that may influence the degree of thinning were identified.
Experimental calculations were performed in Deform-3D with a variation of these factors.
Next, the main factors that could influence the degree of wall thinning were identified. 1.
The radius affects the thinning of the wall due to the fact that it directly affects the "braking" of the workpiece.
Accordingly, the "braking" of the workpiece is influenced more by its mechanical grip on the surface of the die than by the properties of contact of the workpiece with the tool.

Physical and mechanical properties of soft foundation may change strikingly because of the rainstorm, constantly softening phenomenon of soft foundation in full underwater has affected the stability of slope, and engineering has been attracting increasing attention to it [1].
Physical and Mechanical Properties of Soft Rock Soften under Saturated Water Study on the water - rock interaction is one of the new frontiers in geotechnical engineering, and study the change of the mechanics properties of the different types of soft rock in saturated condition, for further discuss on the essence and the regulation of saturated soft rock under the condition of the softening has theoretical significance.
In natural state the rock is relatively complete, hard, mechanical performance is good, when encountering water after a short time rapid expansion, crumbling and softening, which causing the rock mechanics properties quickly greatly reduce [2].
Combined with engineering examples, study on the slide block the stability in different conditions, the results show that on the assumption that the saturated static water, owing to the mechanical properties of rock mass structure surface constant, the stability safety factor of slope change is not apparently.But assuming mass effect in saturated water effect, make the rock mass structure surface mechanical properties of soft, intensity decreases, this would lead to slope slide block stability's influence is more obviously.
