摘要:
|
本文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。通过对一圆形结构物进行有限元计算,重点分析减荷条件下结构物周边上压力分布,计算表明效果明显。

All factors that affecting the earth pressure distribution around buried structures are discussed briefly. The method for improving the earth pressure concentration state by EPS is developed. Through calculation using finite element method, the earth pressure distribution around the tube structure by load reduced method is analysed, which shows that the effect of reducingarth pressure is obvious.
