摘　　要：简要分析了影响上埋式结构物周边土压力分布的各种因素，并建议在结构物顶部填筑聚苯乙烯泡沫塑料来改善其应力集中状态。对一圆形结构物进行了有限元计算，重点分析减荷条件下结构物周边土压力分布，计算表明效果明显。All the factors affecting the earth pressure distribution around top buried type structures are briefly discussed. A measure using the polystyrene foamed plastic filled on the structure’s top for improving the earth pressure concentration state is proposed. A FEM calculation to circular structure under reducing load condition is performed. The calculated result shows that the effect is obvious.
