摘要

根据高速公路路基的变形特点，提出了真空-堆载联合预压法处理软基的三维Biot固结有限元计算模型，将砂井按照实际尺寸划分单元，避免了平面计算方法中的砂井处理的问题，较以往的平面数值方法更接近实际情况。结合修正剑桥模型，对某真空-堆载联合预压试验段进行了计算、分析，结果令人满意。

Abstract

According to the deformation character of expressway foundations

a 3-D Biot consolidation FEM model of soft foundation improved by vacuum combined surcharge preloading method

is proposed. This model can discretise PVD element as its actual factor to avoid the problem of PVD’s simulation in 2-D FEM. A practical engineering of vacuum combined surcharge preloading is computed and analyzed; and the results are satisfied.
