摘　　要：高填方挡墙一直是边坡工程的一大难题,存在成本高、施工难度大等问题。为优化解决此类问题,本文介绍了一种新型挡土墙—自平衡挡墙,在受力分析的基础上建立了计算模型,并结合一个实际工程与传统挡墙进行了受力和造价的对比分析。结果表明,自平衡挡墙利用上部重力式挡墙作为下部挡墙抗力,构思巧妙,结构合理;自平衡挡墙对锚拉条件依赖很少,有很宽的适用范围;在同等条件下,自平衡挡墙造价是悬臂桩挡墙的50%左右,经济效益显著,有较好的应用前景。High fill retaining walls have always been a major challenge in slope engineering with high costs and construction difficulties.In order to optimize and solve these problems,this paper introduce a new type of retaining wall-self-balance retaining wall,establish a calculation model based on force analysis,and compare the stress and cost of a practical project with traditional retaining wall.The results show that the idea using upper gravity retaining wall as the resistance of lower retaining wall is clever and reasonable,the self-balance retaining wall has a very wide scope of application rarely relying on anchoring conditions,the cost of self-balance retaining walls is about 50%of that of cantilever pile retaining walls under the same conditions,with significant economic benefits and good application prospects.
