The strengthening design of the sluice chamber is a renovation from open style to frame, to increase the integral property.
Mining subsidence often produces significant horizontal and vertical movements at the ground surface [5, 6], this will affect the good running of the sluice, and then, will seriously affect the local purposes of flood prevention, irrigation and transportation.
The model is adopted to study the global stability of the sluice in mining subsidence areas through strengthening the foundation, which not considered the interfacial properties between the pile and the soil.
Figs.13 is the safety factors against sliding in the three locations.
The change of safety factors against sliding is analogous to that of the angles of rotation (Figs.16).

The exact solutions in closed-form of the stress intensity factors (SIFs) of the phonon field andthe phason field, and the electric displacement intensity factors (EDIFs) are obtained.
It is well known that the presence of defects such as holes and cracks, greatly affects the physical and mechanical properties of solid materials including QCs.
To our knowledge, the study of QCs functional aspects is very little, especially the study of QCs piezo-electric properties.
The intensity factors at the crack tip are very useful in practice, the vector of the SIFs of the phonon field and the phason field, and the EDIFs inplane can be defined as (24) where,,anddenote the SIFs of the phonon field and the phason field, and the EDIFs respectively.
But the EDIFs not only depends on shear loadings of the phonon field and the phason field, but also depends on the properties of the materials, and has no singularity at the crack tip.

Because of complex features of nonlinearity, time-varying and large inertia, in addition, interference by external factors such as hearth temperature and air flow, exhaust temperature is difficult to be controlled.
Although lower accurate model is required, practice application has proved that the control index is well optimized if hearth temperature and air flow are taken into account as feedforward factors while constructing the control algorithm.
Conclusion Exhaust temperature is a complex object in regenerative furnace and is affected by hearth temperature and the flow rate of combustion air.
Although GPC can, to a certain extent, optimize the control, yet it has no mechanism of diminishing influence of external factors and could not get satisfied result.

In modern manufacturing industries, machining of titanium alloys are very difficult due to generation of high heat in the machining zone due to low thermal properties, results in wear and tear of the cutting tools which directly affects the machining efficiency as well as reduced the tool life.
Out of these eight factors pulse off-time were varied at two levels, and the other seven factors were varied at three levels each.

From the results of ANOVA, tool material (factor-E) has the highest affect on surface roughness of electrode.
Current (factor-B) and pulse on-time (factor-C) significantly affect the surface characteristics.

This is becoming as commonplace as the demands on the mechanical properties.
These are caused by plastic deformations, thermal and mechanical action during drilling process.
This effect of plasticity affects output data strongly and should be corrected.
The function of plasticity factor used with von Mises criteria in MathLab® procedure to rebuild data.
Data from HDrill was reworked to be self-consistent by plasticity factor [7].

ANOVA also can be used to determine the contribution of each factor which influences the properties of the product.
Meanwhile Table 1 is shows the main materials properties.

So that by used simultaneous optimization and overall analysis based on both properties, a set of factors which is considering both properties can be determined.
Meanwhile for flexural strength the result shows that all factors affect accordingly.

The fracture properties were studied with the water to binder ratios (W/B) from 0.18 to 0.14.
Appa Rao et al [7] studied how the coarse aggregate size affect the fracture properties of concrete when the strength of concrete is between 40~70MPa.
As we can see, currently the study on how fracture properties vary with strength or other factors is mainly restricted to normal concrete and high strength concrete.
The study of fracture properties of UHSCM without reinforced is really necessary and it is of great significance for the preparation and promotion of UHSCM.

Using burnt clays in mortars may influence a number of their properties [1]; in particular it is monitored the increase in compressive and flexural strength values.
If it is assumed that the durability of these composites is connected with the number of microcracks affecting them, and their ability to resist the propagation of such cracks, it is possible to quantify this durability using different brittleness parameters.
The performed pilot experiments showed a problem with the fixation of the clip extensometer holder which may represent a general problem for materials with similar structure and properties.
The double-K fracture model Double-K fracture model combines the concept of cohesive forces acting on the faces of the fictitious (effective) crack increment with a criterion based on the stress intensity factor.

The heat source is modeled as a moving heat flux following a double ellipsoid distribution and the temperature-dependent properties of materials are considered.
In order to get a better distribution of the residual stress near the welding line, weld toes dressing is necessary by reheating the weld toes after the first thermo-mechanical coupling analysis in finite element simulation.
The most significant factors affecting the analysis are the heat input rate, the moving speed of the heat source, the thickness of the plate, the geometry of the heating line and the properties of the material.
In the process of analysis, the temperature dependent properties of materials are considered and the heat source moved along loop welds following a double ellipsoid distribution.
After modifying welding line of the finite element model, heat the weld toes again and do the thermo-mechanical coupling analysis once more so as to get a better distribution of the residual stress.

Temperature is one of the important factors affect- ing rock mechanical characteristics, and the temperature field and stress field couple and influence each other, which have an important impact on the stability of geotechnical engineering in cold regions[3-8].
