摘要
回填轻质固化粉煤灰可以提高路堤的临界回填高度,在满足路面工后沉降控制指标的基础上,可以取代软基处治,缩短工期,降低工程造价。运用ABAQUS大型有限元软件,计算和分析轻质固化粉煤灰作为路堤回填材料的土压力及其表面的沉降变形,并进行轻质固化粉煤灰路基回填的沉降分析和试验段观测,可为固化粉煤灰在软土地基路堤回填工程中的应用提供理论依据。
Fly-ash solidified filler can enhance critical filling height of embankment. On the basis of settlement control indices of pavement, it can substitute for softground treatment, decrease construction time, and reduce construction cost. With ABAQUS software, soil pressure and settlement deforma- tion of fly-ash solidified filler are calculated and analyzed. Results of settlement analysis and survey of trial road can provide theoretical basis for its application in softground filling projects.
