摘　　要：论述了加筋土挡墙基于极限平衡理论的设计方法,以宁启铁路海安枢纽内L1DK0+184.953～+339.410段工程为例,介绍了土工格栅加筋土挡墙的方案比选、拉筋设计,并对其进行内部稳定性和外部稳定性进行检算,包裹式加筋土挡墙良好的施工效果也证明了设计的可靠性。The paper discusses the design of reinforced soil retaining wall on the basis of limit equilibrium theory. Taking L1DKO ＋ 184. 935 - ＋ 339. 410 section within Haian junction of Nanjing-Qidong Railway as the example, the comparison of geogrid reinforced retaining wall schemes and its reinforcement design are introduced; and then the internal and external stability of the wall is calculated and checked. The good construction effect of the packaged reinforced soil retaining wall also proves the reliability of the design.
