基于土工格室及加筋的生态边坡加固试验分析

基于生态边坡坡面防护方案，在常规基础上提出了土工格室规格及外掺作物秸秆加筋的改进措施；搭建了室内模拟边坡降雨冲刷试验；控制土工格室规格及外掺作物秸秆加筋变量，分析模拟边坡降雨冲刷数据，综合对比生态边坡坡面防护效果。结果表明 :土工格室及外掺作物秸秆加筋的综合措施能显著提升生态边坡坡面抗冲刷能力，增强边坡防护效果；单一采用土工格室措施的生态边坡冲蚀量相较于裸坡可降低71.27 %，采用土工格室及外掺作物秸秆加筋的复合措施可降低84.65 %；缩小土工格室尺寸有利于降低生态边坡坡面模拟降雨冲蚀量，提升防护效果。

Experimental Analysis of Reinforcement of Ecological Slope Based on Geocell and Reinforcement

In relation to the protection scheme of ecological slope surface, the improvement measures of geocell specification and stiffening of mixed crop straw has been put forward on the conventional basis. An indoor slope rainfall scour test has set up. The geocell specifications and the reinforcement variables of the mixed crop straw have been simulated to analyze rainfall scouring data so that the protection effects of the ecological slope surface can be compared comprehensively. The results show that the comprehensive measures of geocelling and adding crop straw reinforcement can significantly improve the anti-scour ability of ecological slope surface and enhance slope protection effect. Compared with bare slope, the erosion amount of ecological slope improved by geocell alone can be reduced by 71.27 %, while the combined measures of geocell and crop straw reinforcement can be reduced by 84.65 %. Reducing the size of geocell is beneficial to reduce the simulated rainfall erosion on ecological slope and improve the protection effect.
