摘要

运用平面应变比奥固结有限单元法，对南京某钢铁厂江边原料厂采用堆载预压结合塑料排水板处理的软土地基进行了计算，得到了较为理想的效果。计算中将塑料排水板合理地简化成等效砂墙，理论计算结果与实测结果吻合较好。验证了计算方法是合理可行的。

Abstract

A method

drainage with plastic board

was used to improve the soft ground by preloading method for a row material site of a certain steel-iron factory at the bank of the Yangtze river; and it has yielded good results. In this paper，FEM of Biot’s consolidation theory is applied to calculate the consolidation of foundation. The plastic board is rationally simplified to equivalent sand-wall. The measured results are favorably coincident with the numerical results; and that verifies feasibility of the computational method.
