高填土下刚性结构物竖向土压力减荷方法

The Measure for Reducing the Vertical Earth Pressure on the Buried Rigid Structure

提出在结构物顶部填筑聚苯乙烯泡沫塑料（EPS）来减轻上埋式结构物土压力的方法。利用数值分析的手段给出了采用该法后结构物周边上压力的变化，及可供设计参考的土压力计算值。

The measure for reducing the vertical earth pressure on the buried rigid structure under high fill by expanded polystyrene (EPS) is proposed. Many important results are given by finite element method (FEM). Some useful information that can be used in design is obtained.
