- 摘要:
- 太平湖大桥铜陵岸结构面发育，边坡开挖后是否稳定倍受关注。在现场原型调查的基础上，运用3D-FLAC软件对边坡开挖及支护后的变形情况进行了数值模拟。结果表明：边坡开挖后变形较为明显，采取支护措施后变形明显收敛并趋于稳定。模拟结果与实际监测资料基本吻合，说明现场所采用的支护措施是可行的。
- Abstract:
- The structural surfaces are well developed in the slope on Tongling bank of Taiping lake, its stabilization after excavating is much concerned. Based on the field investigation, 3D-FLAC is applied to simulate and analyze the deformation of the slope after it was excavated and retained. The result shows that its deformation after excavating is obvious, but the deformation is convergent and will be stable when the slope has been retained. The simulation and the monitor data of the scene matches well. Therefore, the retaining measure is feasible.
