摘要
山西汾河一级阶地及河漫滩地区地质情况复杂,地基处理不得当则会出现工程事故而造成经济损失。结合实际工程,提出了针对此场地的勘察及地基处理的方法:结合传统勘察方法再配合静探-土工试验法对场地进行勘测,根据灵敏度指标和液性指数将该区域地基分为4类,根据不同的类型采用不同的地基处理设计方案。对于灵敏+液化地基,推荐使用碎石桩+CFG桩进行处理。
The geological situation of Shanxi Fenhe first grade terrace and floodplain is complex and engineering accidents often appeared.Combined with practical engineering,this paper puts forward survey and ground treatment design method.First,use static agent-soil test method to determine the soil sensitivity index,and then combined with liquidity index this region ground can be divided into four categories.According to the different types different foundation treatment design have been used.Recommend gravel pile+CFG pile to treat sensitive+liquefied foundation.
