浅埋强风化岩地质条件下桩基选型分析

Analysis of Model Selection for Pile Foundation Under Shallow Buried Strong-Weathered Rock Condition

在浅埋强风化岩地质条件下,通过多次桩基方案和施工后确定选用预钻孔法静压预制管桩基础。预钻孔法静压预制管桩基础在本地区施工经验欠缺,通过对预钻孔法静压预制管桩进行两次高应变承载力试验分析,为同类地质情况下进行预钻孔法静压管桩施工及高应变检测积累经验。

In the geological condition of s hallow buried strong weathered rock, pre-drilled method static pressure prefabricated pipe pile foundation was selected after pile foundation scheme and construction verification. There is a lack of construction experience of pre-drilled method static pressure prefabricated pipe pile foundation, and twice high strain capacity testing analysis were done, it may gather construction experience for the same geological condition.
