摘　　要：洪水、降雨、水位变化等自然因素会对岸坡坡体内部含水量与坡面侵蚀产生显著影响,严重时导致坡体失稳。为此,以连城闸河道岸坡治理为背景,通过建立降雨条件下岸坡试验模型,分析植被种植对坡体土体抗剪强度参数影响与坡面侵蚀情况。结果表明,植被混种可提高岸坡表层土体黏聚力,提高土体抗剪强度,植被种植虽然会增加浅层土体入渗,降低坡体内部深层入渗,提高坡体稳定性;同时植被种植可降低坡面侵蚀情况。与单一种植相比较,混种条件下能够更好地提高坡体稳定性。Natural factors such as floods,rainfall,and changes in water levels can significantly affect the internal moisture content of bank slopes and cause slope surface erosion,potentially leading to slope instability.To address this,the present study uses the bank slope treatment of the Liancheng Lock River as a case study.By establishing a bank slope experimental model under rainfall conditions,the study analyzes the influence of vegetation planting on the shear strength parameters of the slope soil and the erosion of the slope surface.The results indicate that mixed vegetation planting can increase the cohesion of the surface soil layer of the bank slope and enhance the shear strength of the soil.Although vegetation planting may increase infiltration into the shallow soil layer and reduce deep infiltration into the slope body,it improves the stability of the slope.Additionally,vegetation planting can mitigate slope surface erosion.Compared with single-species planting,mixed planting can better improve the stability of the slope.
