为建立合理的岩溶地面塌陷分析评价和切实的防治设计方法,文中通过对铁路路基典型的岩溶地面塌陷模型进行分类和抽象研究,归纳了岩溶地面塌陷的基本模型和塌陷机制,提出了塌陷物质特征、运移与塌陷通道特征、运移与塌陷动力特征三个岩溶地面塌陷基本因素。结合塌陷模型机理和塌陷基本特征对预测评价方法展开讨论,提出了建立岩溶地面塌陷动态预测评价分析的基本思路和方法。
In order to establish a reasonable analysis and evaluation of karst ground subsidence and practical design of prevention and control, this paper summarizes the basic models and collapse mechanisms of karst ground subsidence by classifying and abstracting the typical karst ground subsidence models of railway subgrade, and presents the characteristics of subsidence material , Migration and collapse channel characteristics, migration and collapse dynamic characteristics of three karst ground subsidence factors. Based on the collapse model mechanism and the basic characteristics of collapse, the paper discusses the methods of prediction and evaluation, and puts forward the basic ideas and methods of establishing dynamic prediction and evaluation of karst collapse.
