Abstract

Abstract: Karst in China has quite great span in geographical distribution or climatic zone，or formation time，and different karst areas have different features． So different treatment measures should be used in different engineering constructions． These factors，such as the growth features of karst，two kinds of basic collapse models，three collapse mechanisms，the in- fluence of foundation stability，and the~undation treatment measures，are analyzed in covered karst terrain．It can provide a reference for construction in covered karst terrain．

Key words: covered karst, karst collapse, foundation stability, foundation treatment

摘要： 我国的岩溶无论是分布地域还是气候带，以及形成时代上都有相当大的跨度，使得不同地区岩溶发育各具特征，工程建设中对其处理措施也有所差异。主要针对覆盖型岩溶，分析覆盖型岩溶的发育特征，岩溶的2种塌陷地质模式、3类主要塌陷机理，覆盖型岩溶对地基稳定性的影响分析，以及岩溶区地基的处理措施，为覆盖型岩溶区的工程建设提供参考。
