摘要
侧向变形对路基沉降的影响不容忽视,基于非线性有限元程序,对路基土的泊松比与分层总和法中的沉降修正系数关系作了定量研究,得出了一些规律性的结论,这对提高分层总和法计算路基沉降方法的工程使用价值具有重要意义。
The influence of lateral deformation to roadbed settlement shall not be ignored. Some quantitative study on the relation between soil possion ratio and the settlement modification coefficient of the layer wise summation method were carried out based on nonlinear finite element program and several conclusions were obtained. It was of great significance for improving the engineering application value of the layer wise summation method in settlement calculation of expressway on soft ground.
