摘    要:根据上海外高桥港区建设的设计要求和地质条件,对不同的吹填粉细砂厚度及不同的下卧层地基,分别采用振动碾压联合动力降水加固技术,低能量强夯联合动力降水加固技术,无填料振冲加固技术进行地基处理。实践证明,这些技术的应用为外高桥港区地基加固开辟了一条新思路,具有一定的社会和经济效益。

关 键 词:地基加固  降水  振动碾压  低能量强夯  无填料振冲  技术

Abstract:According to the design requirement and geographical condition of Shanghai Waigaoqiao Port Area, and in the light of different thickness of reclaimed silty sand and different substrata, various foundation improvement measures including vibro-rolling combining with dynamic dewatering, low-energy dynamic tamping combining with dynamic dewatering, and non-filler vibro-flotation, etc. were taken. Practice proves that the application of this technology has opened a new train of thought for foundation improvement of Waigaoqiao Port rea, and achieved remarkable social and economic benefits.
Keywords:foundation improvement  dewatering  vibro-rolling  low-energy dynamic tamping  non-filler vibro-flotation  technology
