为了判断某建筑物是否位于沉降区内,确定由于地下开采引起的地表沉降范围是十分重要的。众所周知,对于一特定开挖几何形状来说,地表沉降影响区主要受覆盖岩层
In order to judge whether a building is located in the subsidence area, it is very important to determine the subsidence area caused by underground mining. It is well-known that for a given excavation geometry, the surface subsidence area is dominated by overburden
