摘  要:本文在某道路工程真空联合堆载预压基础上,利用有限元的方法,建立三维真空联合堆载预压加固软土路基的有限元模型,对塑料排水板地基进行了简化,适用于实际工程。通过改变模型中的参数设置,实现了不同堆载速率真空联合堆载预压路基,得到不同堆载速率下路基沉降变形规律,可为实际工程提供施工指导。On the basis of vacuum combined surcharge preloading of a road project,a three-dimensional finite element model of soft soil roadbed strengthened by vacuum combined surcharge preloading is established by using finite element method,and the plastic drainage plate foundation is simplified and suitable for practical engineering.By changing the parameter setting in the model,the vacuum combined with surcharge preloading with different surcharge rates is realized,and the law of subgrade settlement and deformation under different surcharge rates is obtained,which can provide construction guidance for practical projects.
