摘要
广东省的地面塌陷主要有自然塌陷及人为塌陷等2种类型。其中人为塌陷包括抽排水塌陷及采空区塌陷。地面塌陷的平面形态多呈圆形、椭圆形、长条形和不规则形等;剖面形态大致可分为竖井状、蝶状、漏斗状及坛状等。从区域上看,地面塌陷的分布特征受地形地貌、地质构造、地下水作用特征、岩溶发育程度、覆盖层条件和人类工程活动等的控制。探讨了广东省地面塌陷的防治对策。
Ground collapse in Guangdong Province mainly includes two types which are natural and human engineering activities, and the latter are composed of two types which are groundwater pumping and the mining collapse. The plane shapes of ground collapse hazard mostly appear as round, ellipse, rectangle and irregular shape etc. As to the profile shapes of ground collapse, they are approximately divided into vertical shaft, butterfly, funnel, ampulliform in shapes and so on. In terms of the regional perspective, the distribution characteristics of ground collapse are controlled by topography and geomorphology, geological structures, groundwater, karst development level, covering layers and human engineering activities. The countermeasures of ground collapse hazard in Guangdong Province have also been proposed in this paper.
