岩溶地面塌陷致塌机理的物理模型试验分析

Physical model test analysis of the collapse mechanism of karst ground

本文从分析某市岩溶地面塌陷的形成条件,结合水动力因素,在概化研究区塌陷地质模型的基础上,进行物理模型试验,研究其形成机制;在物理模型试验的基础上,结合已有的塌陷诱发因素,初步确定致塌模式,为后续进行致塌机制的理论研究提供基础。

Based on the analysis of the formation conditions of karst ground collapse in a city and combining with hydrodynamic factors,this paper conducts a physical model test to study its formation mechanism on the basis of generalizing the geological model of karst ground collapse in the study area.On the basis of physical model test,combined with the existing collapse inducing factors,the collapse causing model is preliminarily determined,which provides a basis for the subsequent theoretical research on the collapse causing mechanism.
