Abstract
To address the potential instability of riverbanks,this study takes the Xinjian River Comprehensive Improvement Project as a background and compares three types of retaining structures:inclined retaining walls,box-type ecological retaining walls,and gravity retaining walls.A 2D finite element model was established to analyze stress-deformation and stability before and after reinforcement,and to assess the impacts of water level fluctuations and pedestrian loads.Results show that the box-type ecological retaining wall provides the best balance between cost,scour resistance,and landscape value.After reinforcement,the deformations at the top and toe of the slope decreased by approximately 40%and 70%,respectively,and the stability coefficient improved from 0.982 to above 1.5,indicating stable conditions.关键词
