摘要
生态护坡具有传统护坡工程不具备的经济性、生态性和社会效应,但护坡基础经常因降雨下渗作用而产生的失稳破坏和影响了生态护坡在工程实际中的广泛应用,降雨方式、降雨强度和边坡地基渗水条件等极大地影响着失稳破坏程度。为此,通过室内物理模型开展了路基边坡的降雨入渗试验,对比研究了裸露路基边坡和采用土工格室植草护坡的降雨渗透试验数据,深入分析了降雨历时、降雨强度对路基边坡稳定性的影响规律,以期为工程实践提供理论参考。
Ecological slope protection has economic,ecological and social effects that traditional slope protection projects do not have.However,the instability and damage of slope protection foundation caused by rainfall infiltration often affect the extensive application of ecological slope protection in engineering practice,while the rainfall mode,rainfall intensity and seepage conditions of slope foundation greatly affect the degree of instability and damage.Therefore,the rainfall infiltration test of the subgrade slope is carried out through the indoor physical model,the rainfall infiltration test data of the bare subgrade slope and the slope protection with grass planting in the geotechnical cell are compared and studied,and the influence rules of rainfall duration and rainfall intensity on the stability of the subgrade slope are analyzed in depth,so as to provide theoretical reference for engineering practice.
