岩溶地区基础选型的思路和建议

岩溶地区不良地质作用较发育、地质条件复杂,在这种地区建设时较难顺利地解决好基础选型及施工方法的选择,基础工程常常进展困难,其主要原因是缺乏应对复杂、有危害的地质条件的基本思路。从方法论入手,寻求解决岩溶地质难题的策略,按照岩溶埋藏较深时考虑回避、中埋时分散地质风险、岩溶浅埋时消除危害的对策,探讨岩溶地区基础选型,提出若干建议和设想。

Recommendations and ideas on the selection of foundation in karst areas

Progress of foundation in karst areas was usually very difficult,it was more difficult to choose foundation type and construction method.The key reason is the lack of the basic ideas to solve the complex,hazardous geological conditions.Starting from the methodology,the strategies were sought to solve problems of karst geology,the selection of foundation type was discussed,a number of recommendations and ideas were proposed.When the karst is buried deep enough,it should consider avoiding the karst.When the karst is not very deep buried,it should spread the loads of structure to reduce geological risks.When the karst is shallow buried,it should eliminate geological hazards.
