Slope slide-resistant pile new and autumn reinforcement method
According to the method, a slide-resistant reinforcement method is adopted for carrying out slide-resistant reinforcement design on the side slope, a method for calculating the residual shear strength of the slide-resistant piles is established, firstly, the position of a dangerous slide surface of the side slope needs to be determined according to a given working condition, and secondly, the residual shear strength of each slide block of the side slope is calculated; designing an anti-slide pile at the position where the residual shearing force of each strip block reaches or approaches the allowable shearing force under a certain safe reserve condition; the cooperative stress state of the rock-soil bodies and the slide-resistant pile system is analyzed, it is guaranteed that all the rock-soil bodies are not damaged, and therefore the optimal matching design scheme of the slide-resistant piles and the rock-soil bodies is found out. The residual thrust of each block of the side slope is calculated, so that the residual shear strength curve of the side slope is in a horizontal fluctuation form and is below the shear strength line; therefore, on the premise that the requirement for slope stability is met, the shear strength of the rock-soil body is brought into full play, and the construction cost of anti-slide pile engineering reinforcement is the lowest.
本发明提出了采用抗滑桩新奥加固方法对边坡进行抗滑加固设计，建立了抗滑桩新奥剩余抗剪强度的计算方法，首先需要根据给定工况确定边坡危险滑面位置，其次是计算边坡各滑块的剩余抗剪强度，在每个条块剩余剪切力达到或接近含一定安全储备条件下允许抗剪力的位置处设计抗滑桩；通过分析岩土体与抗滑桩系统协同受力的状态，确保各条块岩土体不被破坏，从而找出抗滑桩与岩土体的最佳匹配设计方案。通过计算边坡各条块剩余推力，使得边坡的剩余抗剪强度曲线呈现水平波动的形式，且在抗剪强度线之下；由此在满足边坡稳定性要求前提下不仅充分发挥了岩土体的抗剪强度，而且又使得抗滑桩工程加固造价最低。
