| 摘 要： | 土工格室柔性护坡是一种既经济、简便并有绿色环保的护坡模式，越来越被广泛应用于实际工程。但由于该类护坡受周围环境及气候的影响比较大，很多土工格室柔性护坡的失稳破坏是降雨入渗产生的。针对格室防护体系的整体剪切破坏模式，采用极限平衡法建立了降雨条件下防护边坡稳定性分析模型，并通过模拟计算分析了土体含水率、边坡角度、铆钉间距、格室坡长、坡面冲刷和格式深度对其稳定性的影响。研究结果可为土工格室柔性护坡的合理设计和稳定性评价提供技术支持。

| Abstract: | Flexible slope protection geocell is an economic,convenient and eco-friendly technique;and it is increasingly used in practical projects.However,geocell is sensitive to the ambient environment;and it might lose its stability due to rainfall infiltration.In this paper,the shear failure behavior of the geocell system under rainfall infiltration is analyzed.By adopting the limit equilibrium method,a slope stability analysis model is established;and the influences of soil moisture content,slope angle,rivet space,slope length,slope wash and geocell depth on stability are analyzed.The research result would provide technical support for the design and stability analysis of flexible slope protection geocell system. |

| Keywords: | geocell stability moisture content shear strength slope rivet space |
