列车荷载对衡重式挡土墙土压力及稳定性影响研究
Influence Study of Train Load on Balance Weight Retaining Wall Pressure and Stability
摘要
Abstract
Three-dimensional finite difference model of balance weight retaining wall is established using FLAC-3D.The law of soil pressure on the back of retaining wall under backfilling gravity load and dynamic train load is studied and the law of retaining wall horizontal force and stability factor against slide and overturn with train speed is analyzed.The result shows that load influence mainly concentrates in the middle and lower part of upper wall; train speed has little influence on the position of horizontal pressure point and retaining wall stability.关键词
