摘　　要：通过对粉喷桩和塑料排水板堆载预压在软土地基处理机理的分析,提出了在大面积软土地基处理中,可根据场地不同区域对于工后沉降、施工期紧迫性的不同,可运用粉喷桩和堆载预压联合处理。根据对试验区的理论计算和现场实测的对比分析,进一步论证了粉喷桩和堆载预压联合处理的经济性、实用性、可操作性。为大面积软土地基处理在设计和施工方面提供了有用的参考价值。Through the analysis of the mechanisms of powder mixing pile and plastic drain plank preloding compression method in soft ground treatment,it is concluded that these two methods can be combined according to the requirements on settlement after construction and construction time.Based on the comparison of theoretical analysis and on-site tests of experiment area,the economy,efficiency and maneuverability of the combined method is approved.This paper offers an valuable reference to the design and construction of large area soft ground treatment.
