摘　　要：运用FLAC3D数值模拟,对水洛变电站场区高填方地基沉降特征进行研究,结合实际施工过程按开挖前、开挖后、回填及支挡后不同阶段进行模拟计算。结果表明:高填方地基沉降变形具有变形量大、差异沉降显著、沉降变形量与填土厚度关系紧密的特征,与实际情况较吻合。The charaderistics of the foundation settlement of high-fill works in the field of Shuiluo Substation was studied.The simulation and calculation with FLAC3D was conducted in the stages before and after excavation,in backfill and after retaining engineering.The result shows that the settlement deformation of high-fill foundation has the characteristics of large deformation,significant differential settlement,and close relation to the fill thickness.The result of simulation is consistent with the actual situation.
