摘要
波纹钢板加筋挡土墙是一种可实现快速化施工的挡土墙构造形式,具有面板强度高、刚度大,施工速度快,环境扰动小的特点。本文通过采用ABAQUS软件建立有限元模型,在填土、顶部80kPa及120kPa荷载作用下,研究波纹钢板与填土耦合作用对波纹钢板力学和变形特性,并分析了不同深度波纹钢板、土体的水平变形及挡土墙构造物的稳定性。研究表明:波纹挡钢土墙在填土作用下呈倒“S”形,上部呈向外变形,下部呈向内变形挤压土;上部载荷作用下,挡土墙的中间部分会产生凸起,随着载荷的增加,凸起随着向外倾斜的趋势而增加。
Reinforced corrugated Steel retaining wall is a kind of retaining wall structure that can realize rapid construction.It has the characteristics of large strength,high rigidity,fast construction speed and small environmental disturbance.In this paper,the finite element model is established by using ABAQUS software.With the load of 80kPa and 120kPa at the top of the fill,the mechanical and deformation characteristics of the steel corrugated board are studied under the coupling of steel corrugated board and fill soil.The Horizontal deformation of corrugated panel and soil of different depths are analysed.Then the stability of the retaining wall structure are analysed.The research shows that the steel corrugated retaining wall presents a reverse“S”shape under the action of filling,the upper part presents an outward deformation,and the lower part presents an inward deformation extrusion soil;under the up load,the middle part of the retaining wall produces protrusions.As the load increases,the bulge increases with the tendency of the outward inclination.
