摘要

近年来

发现部分采用抗滑桩工程治理后的高速公路滑坡支护结构失效现象时有发生

而公路沿线工程治理后滑坡的稳定性监测评估工作仍没有切实可行的技术标准。针对抗滑桩失效现象

基于抗滑桩内力计算方法——"K"法

通过理论方法试算建立了抗滑桩桩顶位移与桩身最大弯矩、桩径、锚固段长度、悬臂端长度和地基系数之间的关系式

并运用已有文献中的设计实例验证了该公式的合理性

误差在合理范围内。该公式为初等函数组合而成

易于运用到预警系统中。针对具体的抗滑桩设计方案

输入相关参数

可得出桩顶最大位移值

并将其作为判据

结合监测资料对滑坡进行预警预报。

Abstract

Many failure cases of landslides have happened along highways.They were originally supported with anti-slide piles.Up to now

there is still no feasible technical standard for evaluating treated-slope stability for highway construction.Aimed at anti-slide pile failure phenomenon

K method

which was proposed for calculating the internal force of anti-slide pile

was employed to establish a relationship between anti-slide pile top displacement and the maximum bending moment

pile diameter

anchorage length

cantilever length along with foundation coefficient.Then the rationality of the suggested formula was checked with a practical example from a reported case.The error is in a reasonable limit.The formula is simple and easy to be applied in the early warning system.In future

the maximum top displacement of an anti-slide pile can be obtained by using the formula

to evaluate and predict the slope stability

along with the essential monitoring data.
