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.

本论文的创新之处在于，用土拱理论建立了滑坡推力在抗滑桩与坡体之间的传递机制模型，并由此得到了作用于抗滑桩上的滑坡推力计算式以及最大桩间距的确定条件式；建立了抗滑桩与滑坡体相互作用的位移模型，该模型能考虑桩与坡体相互作用过程中二者相对位移的影响，避免了人为假设滑坡推力分布形式的缺陷，给出了其适用条件和计算过程；提出了预应力锚索抗滑桩的改进计算方法，使得预应力锚索抗滑桩的计算理论更加完善，通过实例验证了该方法的适用性和合理性；在预应力锚索地梁力学计算模型研究的基础上，提出了预应力锚索地梁极限状态设计的新思想，给出了该设计方法的实现途径并编制了有限元计算程序，为锚索地梁合理而安全的设计提供了一种新思路。
