水洛变电站高填方地基沉降特征研究

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分析，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，且与实际情况较吻合。

Research on High-fill Foundation Settlement Characteristics of Shuiluo Substation

The settlement analysis and evaluation of high-fill foundation is always a difficult problem in practical engineering. The high-fill works in the field of 500kV Shuiluo Substation was herein taken as the study object and then the simulation and calculation with FLAC3D was conducted in the stages before and after excavation, in backfill and after retaining engineering, then the high-fill foundation was evaluated. The result of simulation is consistent with the actual situation. The settlement deformation of high-fill foundation has the characteristics of large deformation, significant differential settlement, and close relation to the fill thickness.
