摘要
通过对岩溶地区岩体进行钻探取样和室内试验,分析了灰岩岩体的各项特性,并对现场溶洞大小分布规律进行了统计分析,同时介绍了岩溶地区各种桩基处理方法,并结合岩溶地区桩基工程的大量实例,对桩基的嵌岩深度和溶洞顶板的安全厚度进行了分析与讨论。
According to drilling sampling and test indoor in Karst, characteristic of limestone have been analysed, the distributing law of cavities size also has been statistic analysed. All kinds of piles foundation treatment has been introduced. With a lots of cases of piles foundation, the rock-socketed depth and safety thickness of cavities roof have been analysed and discussed.
