许昌县武庄村一村民家院内发生地面塌陷。利用地面及井下调查、测量及地面物探等手段,分析了该坍塌原因。该地区地质构造复杂,下部有多个断裂与背斜,岩体破碎;地下采矿活动和振动导致上伏岩层变形塌落,促使地面下饱水松散层在自身重力及静水压力的共同作用下发生塌陷。 Wuchang Village, Xuchang County, a village homes collapse occurred. The reasons for the collapse are analyzed by means of surveying, measuring and geophysical prospecting on the ground and underground. The geological structure of this area is complex, there are several faults and anticlines in the lower part, and the rock mass is broken. Underground mining activities and vibrations lead to deformation and collapse of the upper strata, which leads to the formation of loose layers of saturated water beneath the ground under the combined action of gravity and hydrostatic pressure Collapse.
