摘　　要：软土高填方路基施工过程中,土内自由水难以及时排出,产生超静水压力,导致路基固结过程延长,沉降变形稳定时间后移,工期滞后.本文在对无砂砼小桩复合地基在后期荷载作用下的变形分析的基础上,研究了软土路基基于变形控制的后处理的优化设计方法.In the construction of thick filling on highway soft-foundation, the free pore water in the saturation soil of highway foundation is seldom discharged immediately, and the excess pore water pressure comes into being, which result in the delay of consolidation and the lag of settlement stabilization time and time limit for a project. On the basis of settlement analysis of small non-sand concrete pile composition under the action of anaphase load, optimal design method of the post-processing of soft-foundation is researched on the basis of settlement control.
