高填方路基沉降影响因素分析

Influencing Factors of Settlement of High-fill Subgrade

为确定各类因素对高填方路基沉降的影响,利用数值模拟分析法进行计算分析,并与现场监测结果对比确定准确性。分析各类因素对高填方路基沉降影响计算结果得出:填方高度和填料容重对路基沉降影响较大,边坡坡度对路基水平位移影响较大,对路基沉降影响较小。与现场监测结果对比得出数值模拟计算结果准确,可作为现场施工的参考。

To determine the influences of various factors on the settlement of the high-fill subgrade,this paper carried out the calculation and analysis using numerical simulation,and its accuracy was verified by comparing it with the field monitoring result.Through the analysis of the calculation results,the filling height and filling capacity weight had great influences on the subgrade settlement,and the slope gradient had a large influence on the horizontal displacement of the subgrade and a small influence on the subgrade settlement.The calculation results of the numerical simulation were in good agreement with the field monitoring results,providing a reference for field construction.
