The transmutative time of the throttle slice under the instantaneous wallop is studied with a finite element software. It is drawn that the time for maximum deformation of the throttle slice is just related to its structural parameters and material characteristics, and the time will be reduced with increase in the slice thickness.

The innovations of the thesis have been shown in several aspects as follows: put forward the transfer mechanism model of the landslide thrust on basis of the soil arching theory, and according to the model the formula about how to compute the thrust acting on the pile and the maximum pile spacing have been deduced. Set up the displacement model about the interaction of the pile and landslide, and their relatively displacement can be taken into consideration when computing the pile, thus the limitation of supposing the distribution of landslide thrust has been avoided, at the same time, the applied condition of the model and the computing procedure have been given. Bring forward the improved computing method of the anti-sliding pile with prestressed cable, which has been verified rational and applicable, making the method more perfectly in theory. Through the study on the mechanical model of the foundation beam with prestressed cable, put up the limit design idea of the structure, and the realization procedure of the idea has been given and programmed with the finite element, which leads to a new thinking for the safe and rational design of the foundation beam with prestressed anchor cable.

According to research on space between wheel and Cart rut traverse curve of single roadway, the width of strip slab was fixed. When there was horizontal loading on slab, contact state between strip slab and base course was studied, and finite element model was established. Comparing maximum principle stress among different load position on slab, it was found that the critical loading position of cement concrete strips pavement was the middle of longitudinal joint.

The rubber seal issue under operating system has been studied by the theory of dynamic sealing. The deformation and stress distribution of rubber material were calculated under the well in-pressure and sealing out-pressure using then-linear finite element. Through the experimental study of the rubber strength and fatigue, the intensity limit and the fatigue life were obtained. According to the study results, a new type of sealing equipment was designed by adding the reinforcing steel bar into rubber core to reduce the maximum shear stress, so as to solve the problems of dynamic seal under hyperbaric pressure.
