岩溶对铁路工程危害很大,是铁路建设中的一个重要工程地质问题。结合我国西南、中南岩溶地区铁路工程地质勘察及施工的实例,对岩溶的发育条件与规律进行了探讨,通过介绍已建成铁路遇到的岩溶问题实例,阐述了岩溶对铁路工程造成的主要危害是突水突泥和路基塌陷,总结了在岩溶地区进行工程地质勘察需要采取遥感解译、物探、钻探综合勘察的工作方法及在岩溶地区铁路工程地质选线原则。对在岩溶地区开展工程地质勘察工作有着一定的借鉴意义。
Karst is very harmful to railway engineering and is an important engineering geological problem in railway construction. Based on the examples of railway engineering geological survey and construction in Southwest China and South Africa karst area, the development conditions and laws of karst are discussed. By introducing some examples of karst problems encountered in completed railway, the main hazards of karst to railway engineering are described as follows: Water bursting mud and roadbed collapse, summarizes the working methods that need remote sensing interpretation, geophysical exploration and drilling comprehensive exploration in engineering geological survey in karst area and the principles of railway engineering geology alignment in karst areas. It is of certain reference to carry out engineering geological survey in karst areas.
