泰安市岩溶地面塌陷的特征及其成因模式分析

Character of Karst Ground Collapse and Analysis on Its Forming Causes Model in Taian

岩溶地面塌陷是岩溶地区因岩溶作用而产生的地面变形现象,是岩溶洞隙上方的岩土体在自然及人为作用下发生变形破坏、并导致地面形成塌陷坑(洞)的一种岩溶地质作用。当它发生于人类活动地区时,就可破坏土地及其附属物,并危及人类生命及财产安全,从而形成地质灾害。就岩溶地面塌陷的特征及其成因模式进行了分析研究,对进一步控制塌陷的发生有重大意义。

The Karst ground collapse is a metamorphism because of Karst function in the Karst area.It is a kind of geological function that the geotechnical mass which the Karst tunnel occur ground deformation failure and lead to ground collapse pit under the natural and human effect.When it occurs in the human activity area and will damage the land and it＇s appendage,endangers vital and property safety and form geological disaster at last.This paper does some research on the character and the causing model of the Karst collapse which has significant importance to control the collapse.
