The invention discloses a landslide monitoring and early warning method based on potential sliding surface middle water content monitoring assisted by rainfall and earth surface displacement mutual verification. The method specifically comprises the following steps: S1, obtaining a real earth surface point cloud; s2, acquiring structural information of a rock core and an underground rock stratum; s3, carrying out three-dimensional geological modeling; s4, establishing a relation model of the water content and the physical and mechanical parameters; s5, inverting the initial state of the slope; s6, installing a rain gauge, simulating a rainfall process, calculating a stability coefficient, and predicting a landslide range; s7, setting an early warning threshold value; s8, installing an earth surface displacement meter and an early warning broadcast; s9, linkage early warning broadcast automatic early warning is carried out; and S10, performing mutual verification by taking moisture content early warning as a main part and taking rainfall and surface displacement monitoring as an auxiliary part. According to the method, through high-precision three-dimensional geologic modeling, 'surface-based general 'of slope profile analysis is improved; the potential sliding surface is simulated and calculated according to the mechanical behavior characteristic numerical value of the rock-soil body, and the defects that the rock-soil body is regarded as a rigid body and the sliding surface is assumed in a strip division method are avoided.

    本发明公开了一种基于潜在滑面中部含水率监测辅以雨量和地表位移互验的滑坡监测预警法,具体包括以下步骤:S1、获取真实地表点云;S2、获取岩芯和地下岩层结构信息;S3、三维地质建模;S4、建立含水率与物理力学参数关系模型;S5、反演斜坡初始状态;S6、安装雨量计,模拟降雨过程,计算稳定系数,预测滑坡范围;S7、设置预警阈值;S8、安装地表位移计和预警广播;S9、联动预警广播自动预警;S10、以含水率预警为主,辅以雨量和地表位移监测进行互验。本发明通过高精度三维地质建模改进了以坡体剖面分析的“以面概全”;根据岩土体自身力学行为特性数值模拟计算潜在滑面避免了条分法视岩土体为刚性体和假设滑动面的缺陷。
