摘要
高水位地区路堤在填筑施工时,容易产生超孔隙水压力,影响路堤的安全。基于有限元方法对同一路堤,在相同施工期下对采用三种分级填筑方法进行研究,结果表明:两级填筑产生的竖向变形最小,但两级填筑和四级填筑产生的超孔隙水压力较大,且安全系数较低。综合分析比较,建议采用三级填筑方法。
The excess pore water pressure is caused easily for embankment construction in the high water level district, affecting embankment safety negatively. Three stage filling technology are researched in the same construction period by the finite element method. The results show that vertical deformation caused by two stages filling is minimum. However, the excess pore water pressure in the process of two stages filling and four stages filling is larger and the safety factor is smaller. After comprehensive analysis, three stages filling method is proposed for embankment in the high water level district.
