Factors influencing settlement of high fill roadbed and control measures
In order to improve the construction level of subgrade engineering,the settlement calculation method of high fill subgrade is summarized.Taking a high fill subgrade of a first-class highway as the research object,a two-dimensional plane calculation model is established by using the finite element software ABAQUS to analyze the impact of the compactness and height of subgrade filler on the subgrade settlement.At the same time,measures such as controlling the moisture content of the filling material,controlling the compaction degree of the roadbed,and dynamically monitoring settlement have been proposed to reduce the settlement of high fill roadbed.
