【摘要】 采空区引发地表变形问题是环境岩土工程领域的重要研究课题。本文以有限元分析软件ANSYS为基础,通过数值模拟方法研究了采空区上方不同性质岩层以及不同上覆岩层组合形式对采空区地表沉降变形的影响。揭示了上覆岩层性质对采空区地表变形的影响规律。更多还原

【Abstract】 Study on subsidence over mined-out area is an important research topic in the environmental geotechnical engineering field.Based on the finite element software ANSYS,it was studied how the rock formation character influences the ground surface settlement using numerical simulation,then the law of ground settlement over mined-out area was revealed.更多还原
