岩溶地区高层建筑基础选型研究

Study on foundation type selection of high-rise building in karst region

介绍了岩溶地区典型的地质情况,针对岩溶地区高层建筑对基础承载力的要求,通过对换填垫层法,人工挖孔桩,钻、冲孔灌注桩,CFG桩复合地基等几种基础类型的经济技术分析比较,得出合理经济的岩溶地区基础形式,供类似工程参考借鉴。

The typical geological conditiorLs of karst region are introduced. According to specifications on bearing capacity of foundation of high- rise buildings in karst region economic and technical analysis is made among replacement method, manual hole digging pile, cast-in-place bored pile, composite foundation of CFG pile and other foundation types. Proper foundation type is selected for foundation works in karst region, which provide good references for similar works.
