摘要
为了研究面板仰角对台阶式高边坡加肋土挡墙受力及变形特性的影响,以实际工程为研究背景,主要考虑了3种不同面板仰角的台阶式加肋土挡墙,通过引入肋-土、土-面板接触单元,利用有限元软件Ansys建立二维模型,对其进行数值模拟计算分析。分析结果表明:当改变面板仰角时,其对台阶式加肋土挡墙的墙面变形情况、墙顶沉降以及基底受压情况产生了较大影响。
In order to study the influences of panel elevation on the stress and deformation characteristics of reinforced retaining wall with stepped high slopes, taking the actual project as the research background, two-dimensional model is established by using finite element software Ansys and introducing reinforcement-soil and soil- panel contact elements, and then numerical simulation analysis will be done on the stepped reinforced earth retaining wall considering three different panel elevations. The analysis results show that the changing of elevation angle has great influence on the deformation of the wall, the settlement of the top and the bottom and the compression of the base of the stepped reinforced earth retaining wall.
