基于工业摄影测量的地下水开采地面沉降试验研究
Experimental Study on the Land Subsidence of Groundwater Mining Based on Industrial Photogrammetry
摘要
Abstract
Groundwater over-exploitation is the main cause of land subsidence,and the use of simulation tests is an impor-tant means to study the land subsidence mechanism.In order to quickly and accurately monitor the transient change process of soil deformation under mining conditions,a set of physical simulation test system of land subsidence based on industrial photogrammetry technology with functions of groundwater recharge,mining and data monitoring and acquisition was devel-oped independently,and the process and characteristics of soil deformation under mining conditions were studied through the test.The test results show that under the constant head boundary condition,the subsidence of each soil layer in the pumping process decreases significantly with increasing distance from the pumping well;under the variable head boundary condition,when the pumping is stopped,the subsidence of each soil layer is still increasing,and the hysteresis effect of soil subsidence is obvious.The MPS marker points are close to the subsidence amount observed by the subsidence scale,and the subsidence change trend is basically the same under the variable head boundary condition,which indicates that the industrial measurement can be used not only for soil deformation measurement,but also better reflect the instantaneous change process of soil deformation under the groundwater level fluctuation condition,with higher sensitivity.关键词
