（1 同济大学，上海 200092；2上海城乡建筑设计院有限公司，上海 201103）[摘要] 在场地地基承载力不足的情况下，工程师通常采取纯桩基础使地基基础能够达到建筑物的承载力要求。然而在这种情况下，常规纯桩基往往忽略了土体对基础的作用，这部分反作用力往往达到上部结构荷载的20%~30%，如果不考虑这部分反作用力，则会造成很大的浪费。在场地地质条件较好的地区，通常场地土的承载力很高，如果能够根据场地情况对地基土进行适当地加固处理，也能使场地地基达到建筑的承载力要求，大大节约造价。对实际工程中采用CFG桩的一些场地处理实例进行了分析。。[关键词] CFG桩; 加固中图分类号：TU473 文章标识码：A 文章编号：1002-848X(2013)S2-0653-04作者简介：杨晓亮，中级工程师，本科，一级注册结构工程师，Email:15810261@qq.com。Comparing and analyzing different CFG projectsYang Xiaoliang(1 Tongji University, Shanghai 200092 China; 2 Shanghai Chengxiang Architectural Design Institute Co., Ltd., Shanghai 201103 China)Abstract: The engineers always use pile foundation when the bearing capacity of the site is not enough. Then they can make the site available to bear the building. But common pile foundation usually ignores the effect from the solid, and the reactive force arrives at 20%~30% of the load of the building in this case. If we don’t consider that case, it might result in waste. In some place, the solid condition is very good. If we process the solid in the site with the solid condition, we will make the foundation available and will save lots of money. Now we list some instance analysis which used CFG pile.Keywords: CFG; reinforce
