摘要
塌陷的形成是多种因素影响和综合作用的结果。地下岩溶的存在是塌陷产生的基本条件之一,可溶岩和水循环条件是影响地下岩溶的主要因素。地下岩溶的发育程度影响塌陷的分布密度,地下岩溶的规模和形态控制或影响塌陷的规模和形态。本文对桂林市临桂新区地下岩溶发育特征进行了分析及其对塌陷的控制与影响进行了探讨,对指导临桂新区塌陷地质灾害防治具有一定意义。
Karst sinkhole occurrences are the results of many potential influential factors.The development of the underground soil and rock cavities is one of the essential factors.The soluble bedrock and the groundwater conditions are the major factors that affecting development of cavities.The degree of karst terrain development,the density of the collapsed sinkholes and the underground soil and rock cavities are the controlling factors affecting sinkhole occurrences.This paper presents the investigation results of karst terrain in Lingui New District of Guilin City.The results can be used in the geological hazards of sinkhole reduction practice.
