摘要
对某输电铁塔采空区地表裂缝进行了调查,定性分析了裂缝对场地稳定性的影响;通过建立三维地质模型,进行了两种工况下采空区地面变形的有限元分析,并对两种工况采空区的场地稳定性进行了分析评价。
By surveying ground crack in gob, site stability affected by crack have been analysised qualitatively. By building three-dimensional geological model, surface deformation and site stability of gob have been analysised and evaluated in two conditions by using finite element method.
