江西省地面塌陷的形成及其防治对策

THE FORMATION OF SURFACE SUBSIDENCE AND COUNTERMEASURE IN JIANGXI PROVINCE

论证了江西省地面塌陷的环境背景条件及其形成、特征、危害、控制因素以及防治对策。结果表明，非岩溶地面塌陷的发生和分布，除了与岩石性质和地质构造有关外，主要受人类工程活动的控制。而岩溶地面塌陷的发生和分布规律，除了与岩石性质和结构、地质构造、地形地貌、上覆第四系土层的性质和厚度等因素有关外，主要受岩溶发育程度和地下水的动力条件控制。

The present paper discusses the condition of environmental background and the formation,property,harm,controlling factors of surface subsidence in Jiangxi province.The result shows that occurrence and distribution of surface subsidence of non-karst land are mainly controlled by activity of mankind engineering in addition to the quality of rock and geologic structure.Occurrence and distribution of surface subsidence in karst region,however,are mainly controlled by degree of karst development and dynamic conditions of groundwater,in addition to factors related to the quality of rock and texture,grologic structure,topographic geomorphic quality of the overlying soil stratum of quaternary and its the thickness,etc.
