　　工程项目内容
　　Because the natural bearing stratum is two layers of clayey silt as well as silty clay, the bearing capacity of natural foundation soil is 110Kpa, which can not answer the needs of designing requirements. Therefore, it needs to design combined footing of CFG pile, in order to meet the requirement that the bearing capacity should be 300kPa. And the final settlement is less than 40mm as well as settlement odds should be less than 0.2％.
　　由于天然地基持力层为2层粘质粉土、粉质粘土，天然地基承载力110Kpa.承载力不能满足设计要求。为此设计要求采用CFG桩复合地基处理，满足基底承载力300kPa的要求，最终沉降量小于40mm，沉降差小于0.2％。
