摘要
Abstract
Based on the finite element numerical method,the influences of top strip load width,offset distance,magni-tude of load,reinforcement length and filling property on the horizontal deformation of retaining wall were comprehensively studied.The results showed that the horizontal deformation of the wall decreased gradually with the increase of the offset distance of the foundation,and the position of the maximum deformation was lowered gradually.When the foundation width or load level was increased,the horizontal deformation of the re-inforced soil retaining wall could be significantly increased,and the former made the position of the maximum horizontal deformation gradually move down,while the latter made the position of the maximum horizontal de-formation gradually move up and eventually stabilize.Increasing the shear strength of the fill could significant-ly improve the deformation resistance of the retaining wall,thereby significantly reduce the horizontal defor-mation of the reinforced soil retaining wall panel;increasing the length of the reinforcement could effectively reduce the horizontal deformation of the wall,when the length of the reinforcement increased to 0.7 times the wall height,the control effect of increasing the length of the reinforcement on the horizontal deformation of the wall panel was weakened.关键词
