In the light of the situation, the artificial foundations were classified according to strengthening mechanism and their damage modes were analyzed. Bearing capacity modification of artificial foundation was analyzed and discussed on the basis of depth modification principle and engineering practice. Some suggestions on depth modification of different artificial foundation were proposed.Keywords: artificial foundation; foundation bearing capacity; depth modification参考文献[1] 王恩远,吴迈. 工程实用地基处理手册[M]. 北京:中国建材工业出版社,2005.[2] 陈仲颐,叶书麟. 基础工程学[M]. 北京:中国建筑工业出版社,1997.[3] GB 50007—2011 建筑地基基础设计规范[S]. 北京:中国建筑工业出版社,2011.[4] JGJ 79—2002 建筑地基处理技术规范[S]. 北京:中国建筑工业出版社,2002.[5] 何广讷. 振冲碎石桩复合地基[M]. 北京:人民交通出版社,2001.[6] 闫明礼,张东刚.
