铜陵小街地面塌陷成因探析

Formation of Land Collapse at Xiao Jie,Tong Ling

依据大量实际资料，系统地分析了铜陵小街地面塌陷分布特征和形成机制。结果表明，在自然和人为造成的开放岩溶水系统下，矿坑疏干排水促进了大气降雨和地表水强烈下渗，产生腐蚀和潜蚀作用而引起塌陷，指出治理和完善区内排水系统是防治地面塌陷产生的关键。

he distribution and the mechanism of the formation of land collapse have been analysed on the basis of a vast amount of field data at Xiao Jie, Tong Ling.The result shows that in the natural and artificial open carst water system,the percolation of surface water and rain water causes corrosion and underground erosion leading to land collapse. Finally it is pointed out that the improvement of drainage system is the key to the prevention of land collapse.
