为了研究基于位移监测的岩质滑带参数拟合反演方法,依托某公路坡顶超高压电塔岩质滑坡实例,采用试验、经验、规范推荐等方法初选岩质滑带计算参数,再运用有限元数值分析方法对滑坡多个断面监测位移数据进行计算拟合,反演求得滑带参数,结合滑坡实际状况评估边坡安全系数,并以此作为计算边界条件,对滑带参数进行进一步验证,同时通过滑坡抢险应急处治对反演参数的合理性进行再次验证。结果表明:通过位移拟合反演得到的岩质滑带参数取值合理正确,计算方法可行,所取参数成功运用于滑坡的抢险治理,对岩质滑坡滑带参数选取具有良好借鉴意义。 In order to study the inversion method of rocky sliding zone parameter fitting based on displacement monitoring and relying on the example of rocky landslide on the top of EHV tower of a highway, the parameters of primary rock slide zone calculation are calculated by the method of experiment, experience and standard recommendation The finite element numerical analysis method is used to calculate and fit the monitoring displacement data of several sections of the landslide. The parameters of the landslide are obtained by inversion and the safety factor of the landslide is evaluated with the actual conditions of the landslide. Based on this, the parameters of the landslide are calculated Further verification, at the same time through the landslide emergency rescue treatment of the inversion parameters to verify the rationality again. The results show that the parameters of rock slide zone obtained by the displacement fitting inversion are reasonable and correct, and the calculation method is feasible. The parameters taken are successfully applied to the emergency management of landslide, which is of good reference for the selection of slide zone parameters of rock landslides.
