widening of subgrade

Disaster characteristic and mechanism analysis on expanded roadbed of advanced level highway
高等级公路路基加宽病害特征及机理分析
What ' s more , the paper , based on a project example , suggested a rational widening embankment structure . by using finite element software - ansys , and according to different environment on soft ground ( including different height of embankment , different thickness of soft ground and different layer - number of reinforcements and so on ) , the paper also analyzed the effects of the geosynthetics which reducing the non - uniform settlement of the new & old embankment , the deformation characteristics and settlement rule of the widening embankment structure , then presented rational widening programs of the embankment structure
另外，本文还以工程实例为背景，拟定软土地基上旧路加宽比较合理的路基结构，并运用大型有限元分析软件ansys进行有限元分析，就软土地基上旧路加宽结构在不同的情况(主要指不同的路基高度、不同软土层厚度、不同的加筋层数等)下，对土工合成材料减少新旧路基不均匀沉降的效果进行分析计算，讨论了软土地基上加宽路堤在不同情况下的变形特征和沉降规律，并在上述基础上，提出不同情况下较合理的路基加宽方案。
