Marc有限元软件在黄土路堤工后沉降预测中的应用
Application of FE Software Marc for Prediction of Settlements in Loess Subgrades
摘要
Abstract
On an experimental site in wet-collapse loess area, a loess subgrade was compacted. Deformation data of gradual loading and instantaneous loading were measured respectively. It has been concluded that the deformations of gradual loading were larger than those of instantaneous loading and the difference between two values reduced to a fixed number with the increase of vibrating compactions. MSC. Marc is an international advanced nonlinear finite element analysis program based on displacement method. Observation data of settlements after construction was simulated and analysed by the software. The deformations at subgrade center reduced toward two sides and a pot-shaped settlement regulation was observed.关键词
