强夯法和冲击碾压法是地基处理中常用的两种比较成熟的技术,由于应用范围、加固特点和施工工艺等方面的差异,在实际工程中应用后的效果是不同的。本文根据上海地区的土层特点和工程设计要求,对上海某试验场地分别采用强夯法和冲击碾压法进行地基处理,通过地表沉降观测、孔隙水压力监测和地下水位监测,对两种方法的处理效果进行了对比分析,总结了各自优点和不足,可供类似工程参考。
Dynamic compaction and impact rolling are two commonly used techniques in foundation treatment. Due to the differences in application scope, reinforcement characteristics and construction technology, the effect after application in actual engineering is different. According to the characteristics of soil layer and engineering design in Shanghai area, this paper applies the dynamic compaction method and impact rolling method to treat the ground in Shanghai. Through the observation of surface subsidence, pore water pressure monitoring and groundwater level monitoring, Of the treatment effect of a comparative analysis, summed up their advantages and disadvantages, for a similar project reference.
