Results show that diagonal tensile stress is the main factor of crack, crack easily take place in the lower surface, where obviously exist a region of stress concentration in 45°direction.
The service life and the utilizing effect of the metal base not only affect the cost of per ton steel, but also have a very significant impact on ladle turnover , production scheduling , continuous casting , and the labor intensity of operators[1].
Therefore, the temperature and stress fields of the metal base were calculated by the FEM method; analyzing the crack causes and the main factors of impacting the life had important guidance purpose to solve the problem of base damage[2-4]. 2 Thermo-mechanical coupling model of the Metal base 2.1 Assumptions in the mode With the simultaneous use of ladle, the course of the metal base work was as follows: base mounting →the first pouring →ladle placed cooling →​​pouring →ladle placed cooling, and so on.
Due to the material properties of the metal base was similar to the steel plate, it was regarded synchronous expansion as the bottom of ladle.
Among with time the stress gradually decreases, the value is decreased to 542MPa until 2h. 4 Conclusions （1）The upper surface stress of the metal base is less than the stress of the lower surface at different times in use； （2）Diagonal tensile stress is the main factor of the cracks； （3）Stiffen ribs to the place where is easy to appear the crack; try to make the structure of the base symmetric so that the stress on the base can be more evenly distributed.

The forming properties are simultaneously dependent on the heat transfer characteristics in the coil which are to consider in the reverse hot rolling modelling.
These are generally used for the prediction of the roll force and power, microstructure changes and mechanical properties during the continuous finishing hot rolling [2, 4, 7–13].
In the case of reverse strip rolling, the rolling velocity is limited and forced convection do not affect the heat transfer strongly.
The conduction heat transfer coefficient in the roll gap is introduced and is affected by factors such as lubricant, temperature gradient between rolls and strip, deformation gradient, scale formation and other factors.

Several aspects were already studied in that technology and influence whether the mechanical properties of the part, the thickness of the layer is one of the factors that has the greatest effect on the part and can easily be adjusted and controlled but depend of the powder size [5].
Other works study the effect of anisotropy in sintering parts and observe a variations around 1mm depending of several factors [8].

It concluded the present work on the two main factors which influence the bearing capacity of rock-socketed pile most.
In summary, the factors affecting the capability of rock-socketed pile can be divided into two aspects: in one hand, pouring concrete under water may lead to the problem of pile capability and geometric dimensions, such as eduction, necking, broken, etc; in the other hand, the problem of pile side soil and bottom sediment caused by rock characteristic, hole wall roughness and mud quality problems, etc. 2.1 Influence of rock-socketed depth With the research work goes deeper, scholars find that increasing the length can not always be effective to improve the capacity of pile.
It is a hot issue simulating the mechanical behavior of pile-rock interface under construction factors. 3.3 failure mechanism of rock-socketed pile The destruction and instability phenomena of rock-socketed pile often occur.
It concluded the present work on the two main factors which influence the bearing capacity of rock-socketed pile most.
Finite element analysis of load-bearing properties of large diameter rock-socketed single pile[J].

The mechanics properties of the contact surface between beam and rock can be simulated more accurately by using the finite element method, so as the deformation and force analysis of the whole crane girder.
The anti-sliding stability safety factor [KS] =1.30, the tensile-strength safety factor of tensile anchor bolt [Kt] =1.60, the corresponding design allowable tensile stress [σ] =210MPa.
From the calculation results, we know that the axial tension of upper tensile anchor bolt and tensile-strength safety factor of result two is same as result one ,but the anti-sliding stability safety factor is bigger than result one.
Some mechanical properties of rock and crane girder are not very homogeneous, which causes great difficulties to use the finite element method for simulation.
The rigid body limit equilibrium method is flawed, and the finite element method is easy affected by the parameters.

The impact of blasting vibration on stability of rock slope is mainly manifested in two aspects: firstly, repeatedly blasting vibration load disturbance causes further expansion of jointed rock mass and increased loose deformation which results in the deterioration of mechanical properties of rock and make the road cutting slope unstable, especially high and steep slope.
Physical and mechanical parameters of the site area of limestone is as Table 1shows Table1 The physical and mechanical parameters of limestone Rock types Modulus /GPa Internal friction angle /0 Cohesion /MPa Tensile strength /MPa Density /Kg·cm-3 Limestone 45 36 25 6 2550 Calculating Model And Parameter Selection According to foundation excavation terrain conditions, the numerical simulation takes the final object of the excavation slope as a blast load.
To simplify the analysis process, we assume the cutting numerical simulation of rock slope excavation as the following: (1) Equivalent uniform loads acting on the same line hole blasting area where the plane with center line, Load strength depends on the medium properties, distribution methods and the charge quantity
These new inclined cracks may affected the original structures of the rock slope, the transfixion cracks might occur, it would reduce the anti-sliding ability of the rock slop, form slippery body and result in the un-stability of the slope.

To ensure the results of numerical simulation being meaningful, mechanical and physical properties assigned to numerical model should be determined as accurately as possible.
Unfortunately, mechanical properties derived based on laboratory and field test are often dispersive due to the influence of joints and fissures [1].
Back analysis techniques are nowadays frequently used to determine the mechanical properties of rock mass by using field measurement of displacement induced by excavation.
The Mohr-Coulomb plasticity model was assigned as constitutive mechanical model.
