摘　　要：岩溶在我国南方地区分布较广,作为一种特殊的不良地质作用,一直以来都是工程建设的棘手问题。随着城市建设的发展,位于岩溶场地的工程建设项目越来越多,特别是浅覆盖石灰岩地区,上履松软土层时,勘察、设计、施工均是个难题,一旦处理不当,势必影响工程的顺序开展。本文通过某位于浅覆盖型岩溶区的典型项目成功建设实例,提出了上履松软地层的浅覆盖石灰岩地区,合理的勘察设计顺序及应注意的若干问题,为国内岩溶地区开发建设勘察设计工作提供经验。Wider distribution of karst in southern China,As a special kind of adverse geological,Sting has always been the engineering construction.With the development of urban construction,more and more construction projects at the site of the karst,In particular,shallow coverage of the limestone region,On V soft soil,survey,design,construction is difficult,if not handled properly,is bound to affect the order to carry out the project.Through a typical project successful construction of instances in the shallow cover karst area,the limestone areas of shallow cover on V soft strata,survey and design order and should be noted that a number of issues,development and construction survey and design work for the domestic karst areaexperiences.
