摘要
为揭示预制模块式空心面板加筋土挡墙的面板连接稳定性影响规律,基于极限平衡理论,深入研究了模块式空心面板加筋土挡墙面板连接稳定性。考虑了模块面板的空心率和倾斜角度,计算了筋材连接拉力和面板连接抵抗力,并建立了相应的稳定性分析方法。通过与已有文献结果对比验证了该方法的有效性。进一步对不同因素开展了参数分析。结果表明,增加模块空心率、减小填土内摩擦角和增加加筋间距会降低面板连接稳定性,对挡墙中下部的影响尤为显著;倾斜的加筋土挡墙面板连接稳定性显著降低,对挡墙中上部影响更为显著。
To reveal the influence of prefabricated modular hollow panel reinforced earth retaining wall on panel connection stability,based on the limit equilibrium theory,the stability of modular hollow panel reinforced earth retaining wall panel connection was deeply studied.Considering the hollow ratio and tilt angle of the module panel,the tensile force of the reinforcement connection and the resistance of the panel connection were calculated,and the corresponding stability analysis methods were established.The effectiveness of this method has been verified by comparing it with existing results in the literature.Further parametric analysis was conducted on different influential factors.The results show that increasing the module void ratio,reducing the internal friction angle of the fill,and increasing the reinforcement spacing will reduce the stability of the panel connection,with a particularly significant impact on the middle and lower parts of the retaining wall.At the same time,the stability of the inclined reinforced soil retaining wall panel connection is significantly reduced,with a more significant impact on the upper part of the retaining wall.
