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.
