基于空间协同作用的框架式抗滑桩力学分析模型考虑了桩、梁、岩土之间的相互作用及桩间土拱效应,运用空间协同分析机理对框架式抗滑桩结构的内力和变形规律进行分析,较好的弥补了当前主要采用桩土效应对多排抗滑桩进行受力分析的局限性.根据框架式抗滑桩受力模型的基本假定,采用分段计算方法,以框架式抗滑桩的滑动面为分界将桩体结构分为两段,综合运用土拱效应、平衡协调原理及弹性地基梁方法,分别建立框架式抗滑桩上下部分的受力计算方程,给出该模型受力计算的数学解析方程组求解法,并采用MATLAB对方程组进行编程计算,结合工程实例的实验结果进行对比分析该数学解析法的正确性.
The mechanical analysis model of the frame-type anti-sliding pile based on the space synergy takes into account the interaction between the pile, the beam and the soil and the soil arching effect between the piles. The internal force and deformation of the frame-type anti-slide pile structure , Which make up the limitation of stress analysis of multi-row anti-slide piles, which is mainly based on the pile-soil effect.According to the basic assumptions of the frame-type anti-slide pile force model, The sliding surface of the anti-slide pile is the boundary, and the pile structure is divided into two sections. By comprehensively using the soil arching effect, the principle of balance coordination and the method of elastic foundation beam, the force calculation equations of the upper and the lower part of the anti-slide pile are established respectively. The model is solved by mathematical solution equations of force calculation, and the equations are programmed and calculated by MATLAB. The correctness of the mathematical analysis method is compared with the experimental results of engineering examples.
