摘　　要：以四川西江河河道改道工程为研究对象,采用有限元软件对河堤挡墙不同施工工况稳定性进行对比分析。研究结果表明:挡墙背的填土材料对挡墙稳定性影响较大,当回填黏土高度到达8 m时,挡墙开始产生倾斜的趋势,同时在左侧墙脚位置开始出现塑性区;采用砾石土回填能够大大提高挡墙的稳定性,使挡墙处于稳定状态。Taking the river improvement project of Xijiang River channels in Sichuan as the research objec,the stability of embankment retaining wall under different construction conditions is compared and analyzed by finite element software.The results of thr research show that the backfill material at the back of the retaining wall has a great influence on the stability of the retaining wall.When the backfill clay reaches 8 m,the retaining wall begins to tilt,and plastic zone begins to appear at the left wall foot.Meanwhile,backfilling with gravel soil can greatly improve the stability of the retaining wall and keep the it in a stable state.
