The number of tunnels built in the high-altitude and cold conditions is increasing continuously followed with the transfer of economic construction to the western part of the country, the temperature change is one of the important factors that affect the mechanical properties of the rock, and has a significant impact on the stability of the geotechnical engineering in cold regions[3-7].

The size, pattern and depth of the soil trough depend on various factors such as the frequency and amplitude of the cyclic movement, depth and type of the abutment wall and the properties of the backfill [7].
However, an effective and comprehensive solution will require an adequate understanding of the dominant factors that affect the response of soil subjected to cyclic wall movements.

The study was conducted to establish an understanding of the dominant factors that affect the soil response due to wall movements.

D.M.Tanner concluded that package was one of the main factors which affected MEMS sensor reliability, and it would influence the output performances of the sensor[6].
When acceleration affects the sensor, the resistance change of piezoresistors result in the sensor output the signals.
Therefore, the properties of die adhesive will also affect the output performances of the sensor.
(a) sensitivity test with stainless steel package shell (b) sensitivity test with ceramic package shell Fig.7 Sensitivity test on the different high-g accelerometer According to the reference [12], the difference of sensitivity for MEMS accelerometer packaged with two different shell materials is mainly due to the different propagation properties of impacting stress waves in ceramic and stainless steel materials.

In addition, the ore experiences a metallogenic tectonic movement and the properties of the surrounding rock are broken, therefore, strong tectonic stress may exist.
To sum up, 3# alteration zone really exists and has an adverse effect on the stability of the slope; nevertheless, the influence degree is very limited, applying no main control factors[4].

Domestic and foreign scholars’ studies mainly concentrate on the mechanical properties of FRP reinforcement and corrosion resistance.
The mechanical properties of GFRP gluten indexwere shown in Table 1.
Table 1Mechanical properties index of GFRP gluten Diameter [mm] Sectional area [mm2] Tensile strength [MPa] Tensile resistance [KN] Ductility [%] Elastic modulus [GPa] 18 254.3 705 150.6 1.57 43.0 25 490.6 659.5 298.1 2.02 43.4 32 803.8 590.6 393.8 2.42 42.8 (2)Concrete material. 32.5 ordinary Portland cement and crushed stones whose size is less than 18mm were used.
With the same diameter, the bond strength of thread GFRP boltis about 2 times the light gluten, but the slip is only about 70% of the light gluten.Because the bond strength of thread bolt is mainly composed of chemical adhesion, friction and mechanical interlockingforce, however, the mechanical interlockingforce affects most.
The results show that the improvement of rock and soil properties can significantly improve the anchoring effect and reduce the slip failure.

In the present brief communication we extend the discussion on the mechanical properties of metals produced by severe plastic deformation.
The accent is placed on the mechanisms of strengthening and the role of different metallurgical factors in strengthening.
Hence, the materials employed in the present study are supposed to involve all these mechanisms in various combinations, which is useful to clarify the role of individual constituent mechanisms in the resultant properties of UFG SPD metals.
Surely, the number of passes which is required to form the high-angle grain boundaries is different for different materials, being dependent on various metallurgical factors such as the stacking fault energy, for instance.
It is worth noticing that the strain hardening exponent n is the same for both K18 alloys, i.e. strengthening in Au-25Ag and AuAgCu occurs in the essentially same way despite considerably different properties of solid solutions.

Initial surface of workpiece Finished surface of workpiece Abrasive grain of grinding wheel Tribological action Brittle fracture Plastic deformation Furrowing action Fig.1 Generating model of grinding surface Fig.2 Material removal modes in grinding process Influential factors of material removal modes in ultraprecision grinding In ultraprecision grinding, there will be four different material removal modes, and influential factors may be derived from grinding wheel, workpiece, grinding parameter and some accompanying phenomena[3].
Influential factors from grinding wheel include specialties of wheel and their truing and dressing state, and wheel specialties include wheel’s shape and dimension, types of abrasive material, grain size, concentration of abrasive, hardness of wheel, types of bond, organization structure and so on.
Influential factors from workpiece include mechanical properties of material and microstructure of parts, and mechanical properties involve strength, hardness, brittleness number and fracture toughness, microstructure means content of impurities, Porosity rate, dislocation defects and crystal grain size.
And for a certain cutting depth , there are: ， And so, （3） Apparently, the ratio will decrease as the depth of cut decreases, and the specific depth at which a brittle-ductile transition occurs is a function of the intrinsic material properties, such as plasticity and brittleness.
Influential factors of dynamic balance state includes different initial state of wheel surface, non-liner electrolysis action, electrolyzing condition and machining parameters preseted only based on experience or guesstimate.

Introduction Generally, structures are exposed to a number of factors that negatively influence their reliability (material degradation due to environmental influences, changes in the load intensity, accidental actions - for example a vehicle impact, etc.) during lifetime.
FRP confinement induces the triaxial state of stress [1], [7], which leads to increase of the mechanical properties of the concrete as a base material.
Fig. 2 Principle of strengthening by confinement – lateral stress Factors influencing effect of confinement.
Initial relations were derived mainly for cross-sections reinforced resp. strengthened with steel reinforcement, but they are generally valid if different mechanical properties of strengthening materials are taken into account.
Together with the test specimens, concrete beams and cubes were manufactured in order to determine required properties of concrete - concrete compressive strength and modulus of elasticity.

Constructive problem solving processes gradually evolved as increased knowledge about materials and their properties and modeling as growing complexity and the complexity of the products.
Perhaps the most affecting to the constructive problem solution the using of computers and their application is compared with the invention of the printing press.
Since the problem is not wholly described now, it is difficult to cope with the dynamic properties of the unknown environment

An increase in the loads transferred by a harmonic drive also raises the values of the forces affecting the teeth of its toothed rim.
The physical model not only entails the physical properties of the material the tooth is made of, but also the manner in which it is both loaded and supported.
The last of the factors mentioned are ultimately decisive for the correct formulation of the boundary task that is to be solved by means of BEM.
The material properties assumed for the calculations have been provided in Table 1.
