Method for determining horizontal displacement of wall surface of modular reinforced soil retaining wall in limit state
The invention relates to a method for determining horizontal displacement of the wall surface of a modular reinforced soil retaining wall in the limit state. The retaining wall comprises a wall panel,filled soil and ribs. The wall panel is regarded as being formed by modular bricks layer by layer, the actual stress characteristics of the modular reinforced soil retaining wall in the limit state are analyzed, the modular bricks are taken as a research object, the static balance analysis is carried out on the modular bricks, and a calculation formula of the horizontal displacement delta h of the wall surface of the modular reinforced earth retaining wall in the limit state is determined by means of the connecting force P of the wall panel and the ribs at different heights of the modularreinforced earth retaining wall in the limit state, wherein in the formula, K serves as the stiffness of the ribs, psi serves as the soil filling expansion angle, phi serves as the inner friction angle of the wall panel, H serves as the height of the top of the wall panel, and Z serves as the calculation depth from the top of the wall panel along the wall. According to the method, the actual stress characteristics of the modular reinforced earth retaining wall in the limit state are considered, and the size of the horizontal displacement of the wall surface of the reinforced earth retaining wall in the limit state can be directly obtained.
本发明为一种模块式加筋土挡墙极限状态墙面水平位移的确定方法，挡墙包括墙面板、填土和筋材，将墙面板看作为由一层层模块砖垒成，分析极限状态下模块式加筋土挡墙实际受力特征，以模块砖为研究对象，通过对模块砖进行静力平衡分析，由极限状态下模块式加筋土挡墙不同高度处墙面板与筋材的连接力P，确定模块式加筋土挡墙极限状态墙面水平位移δ的计算公式为；式中：K为筋材刚度；ψ为填土膨胀角；为填土内摩擦角；H为墙面板顶部的高度；Z为从墙面板顶部沿墙高的计算深度。该方法考虑极限状态下模块式加筋土挡墙实际受力特征，能直接获得极限状态下加筋土挡墙墙面水平位移的大小。
