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參考文獻[1] 王恩遠,吳邁. 工程實用地基處理手冊[M]. 北京:中國建材工業(yè)出版社,2005.[2] 陳仲頤,葉書麟. 基礎(chǔ)工程學(xué)[M]. 北京:中國建筑工業(yè)出版社,1997.[3] GB 50007—2011 建筑地基基礎(chǔ)設(shè)計規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2011.[4] JGJ 79—2002 建筑地基處理技術(shù)規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2002.[5] 何廣訥. 振沖碎石樁復(fù)合地基[M]. 北京:人民交通出版社,2001.[6] 閆明禮,張東剛.
