| 摘 要： | 强夯加固处理是山区土石混填路堤施工的有效措施,夯沉量作为施工检测的重要指标,在土石混填中研究甚少。论文采用大型有限元软件ABAQUS,建立了三维数值模型,对夯沉量随夯击次数的变化进行了系统研究。与实际工程对比,得出2 000 kN.m夯击能10击后的模拟夯击沉降量为1 158 mm,与实测结果976 mm相比,满足误差精度要求,证明了建模分析的可行性。

| Abstract: | Compacted reinforcement is an effective measure for rock-soil filled embankment construction in mountainous area.Compacted settlement,as an important index in construction detection,has been rarely studied in rock-soil filled embankment.In this paper,three-dimensional numerical model is established using large-scale finite element software ABAQUS to carry out systematic study on settlement with compaction times.Compared with practical engineering,the simulated compacting settlement is 1158 mm after 10 times of compaction with compacting energy of 2000kN·m,satisfying error precision requirement compared with 976mm from actual measurement,which proves the feasibility of modeling analysis. |
