The invention discloses a cantilever anti-slide pile side pressure monitoring method. The method comprises the following steps that a coordinate positioning acquisition instrument and a monitoring point calculation module are arranged; dividing monitoring grids on the left side surface or the right side surface of a cantilever section of the slide-resistant pile, and selecting displacement and pile side pressure monitoring points; acquiring coordinates of the monitoring points through a coordinate positioning acquisition instrument on the ground; turning point positions of the front and rear surfaces of the pile body are calculated and determined through a monitoring point calculation module; monitoring point displacement and deflection distribution are determined through pile body deformation and non-uniform external load characteristics of a pile-soil interface of a load-bearing section of the cantilever pile; and a lateral pressure fitting analytical formula of any point on the pile side of the cantilever anti-slide pile is obtained through deflection conversion of the monitoring point of the load-bearing section of the cantilever pile. According to the method, the problems of slide-resistant pile breakage, side slope landslide, human misjudgment factors, complex technology, high risk, high monitoring cost and the like caused by unreasonable monitoring schemes or monitoring results of slide-resistant pile turning point positions, pile body deformation and pile side pressure during service can be solved; the rapid monitoring method has the advantages of strong environmental adaptability, safe operation, simple construction, low cost and high precision.
本发明公开了一种悬臂抗滑桩桩侧压力监测方法，包括以下步骤：设置坐标定位采集仪和监测点计算模块；在抗滑桩悬臂段左或右侧面划分监测网格，选取位移和桩侧压力监测点；通过地面上坐标定位采集仪获取监测点的坐标；通过监测点计算模块计算确定桩身前后两面的转点位置；通过桩身变形和悬臂桩受荷段桩土界面非均布外荷载特征确定监测点位移和扰度分布；通过悬臂桩受荷段监测点扰度换算获得悬臂抗滑桩桩侧任何点侧向压力拟合解析式。本发明方法可以克服服役期间抗滑桩转点位置、桩身变形和桩侧压力监测方案或监测结果不合理造成的抗滑桩断裂、边坡滑坡和人为误判因素、技术复杂、危险性较大、监测成本较高等问题，保证了快捷监测方法具有环境适应性强、操作安全、施工简捷、成本少、精度高。
