摘要
在调查区内现存地面塌陷的基础上,根据采空区分布及相关数据,分析计算采空区影响范围及程度。采用概率积分法计算地面的移动和变形值,从而绘制出地面塌陷沉降等值线图,为当地政府采取防治措施及进行相关决策提供依据。
The influence range and degree of the mined--out areas are calculated, based on the status quo survey of ground collapses. The probability integral method is used to calculate the ground movement and deformation values and then draw out the ground collapse and settlement isoline map. This provides the basis for the local government to take control measures and make related decisions.
