路基拓宽变形影响因素分析与处治方法研究

摘要

Applying finite element method, the paper analyzes the influential factors of road expansion deformation from aspects of expansion width, expansion height, compacting modulus and expansion methods and so on, and puts forward methods of reducing uneven subgrade settle- ment, so as to effectively guarantee highway construction quality.%利用有限元分析方法，从加宽宽度、加宽高度、压缩模量、加宽方式等方面分析了路基拓宽变形的影响因素，提出了减少路基不均匀沉降的方法，从而有效地保证了高速公路的施工质量。
