| 中文摘要: |
| 本文通过室内模型试验，研究了位于软弱地基中的重力式挡墙的抗滑稳定性和齿坎对挡土墙的抗滑作用。通过试验研究得出结论：由于齿坎的存在，可大幅度地提高挡土墙的抗滑稳定性，在软弱地基中尤为明显；当挡土墙达到滑动破坏时，齿前的土压力达到被动土压力值，而齿后的土压力接近于零；对于无齿挡墙，滑动破坏面位于基底表层的土体内。 |
| 英文摘要: |
| The stability of gravity retaining wall with tenon built on weak foundation is stuied in model test. The result shows that the stability of the retaining wall is greatly improved due to the effect of tenon. during the sliding failure, the soil pressure acting on the front face of tenon reaches passive and on the rear face the soil pressure is appromimately equal to zero. Thus the sliding resistence is greatly elevated. |
