摘要
根据场区的工程地质条件和高填方资料建立地质模型,运用现场试验所获得的参数和3DFLAC程序对高填方块碎石夯实地基的变形进行数值模拟,分析地基沉降和侧向变形及可能发生剪切破坏的位置,模拟和分析结果与实际基本一致。
Based on airport construction practice in southwest China,this paper studied the deformation behavior of block and gravel fills. With engineering geological conditions and settement data,a prediction model was established .Three dimensional simulation was conducted using 3D FLAC software to simulate the deformation process of highfills in airport engineering,especially surface settlement,lateral deformation,and potential shear failure plane. Simulation results are similar with practice.11 figs,8 refs.
