为研究充填体力学性质对地层变形规律的影响,基于2种不同力学性质的充填体,采用FLAC对地层变形进行数值模拟,实际选择充填体II进行地面变形监测。研究结果表明:充填体力学性质越强,关键层及地面下沉量越小,地面局部倾斜及曲率越小,地层变形程度越小;采用充填体II的地面最大下沉值、地面最大局部倾斜、地面最大曲率的监测值与数值模拟结果基本吻合,地面为稳定场地,地面建筑物安全。
In order to study the effect of filling body mechanical properties on the formation deformation, based on two kinds of filling bodies with different mechanical properties, FLAC was used to simulate the formation deformation, and the filling body II was selected for ground deformation monitoring. The results show that the stronger the mechanical properties of the filling body, the smaller the critical layer and the subsidence, the smaller the local inclination and curvature of the ground surface, and the smaller the deformation of the ground surface. The maximum subsidence value of the filling body II, , The monitoring value of the maximum curvature of the ground basically agrees with the numerical simulation results, and the ground is a stable site and the safety of the ground building.
