摘　　要：道路路基处理不良土时,可采用换填、物理改良、化学加固、抛石挤淤、注浆及桩处理等方法。群桩加固是处理不良土路基的一种有效形式,在实际工程中运用广泛。本文对南宁市沙江路桩土复合路基进行有限元模拟,分析不同桩径、不同材料对不良土的沉降及剪应力的影响。根据模拟结果,选出较优参数,为实际工程做参考。When dealing with poor soil in road embankments,methods such as replacement and filling,physical improvement,chemical reinforcement,stone throwing and silt squeezing,grouting,and pile treatment can be used.Pile group reinforcement is an effective form of treating poor soil roadbed and is widely used in practical engineering.This article conducts finite element simulation on the pile soil composite roadbed of Shajiang Road in Nanning City,analyzing the effects of different pile diameters and materials on the settlement and shear stress of poor soil.Based on the simulation results,the optimal parameters are selected to provide reference in practical engineering.
