Shi Tiejun, Zhang Xiaolian, Hu Xianhua

Abstract: For taking advantage of capacity of high bearing capacity pile in composite foundation, top area of pile is expanded by CFG pile. Applicability of high bearing capacity pile in reinforcement of large scale oil tank foundation and regulation of pile-soil composite foundation settlement are investigated, which reveal problems in application of high bearing capacity pile for reinforcement of large scale oil tank foundation. Some conclusions are obtained.
Keywords: tank foundation; foundation reinforcement; expand top pile
