| 摘 要： | 张家坪滑坡具有多级多层的复杂滑体结构,本文选取最典型的断面开展了大型地质力学模型试验,模拟了边坡的开挖过程,并采用均匀毛细浸润技术研究雨水作用下的坡体稳定性,通过有无支挡的两阶段试验对比,分析了多级多层复合滑坡的变形失稳机制和工程病害,以及相应抗滑支挡结构的加固效果。

| Abstract: | The Zhangjiaping landslide has multi-layers and multi-levels. To model excavation of the slope, the most typical cross-section is selected as the physical model prototype. During the experiment, the slope stability is simulated under the influence of rain by even capillary flooding method. By comparing two experiments with and without an anti-slide structure, the authors gain an insight into the destabilization mechanism of this slope, and the reinforced effect of anti-slide structure. |
