Abstract:

?针对平动模式下的刚性挡土墙,提出了考虑土拱效应的非极限主动土压力计算方法。考虑墙体平动位移对墙后填土内摩擦角与墙土界面上的外摩擦角的影响,建立了内外摩擦角与位移之间的关系式。对未达到极限位移的挡土墙,分析墙后小主应力拱的应力状态,并结合位移与摩擦角之间的关系,把主动侧土压力系数与挡土墙位移联系起来,将其用于水平微分单元法求解平动模式下挡土墙非极限主动土压力,给出了考虑土拱效应的非极限主动土压力分布、合力及作用点的理论公式,并与不考虑土拱效应的非极限主动土压力计算方法进行了比较。结果表明:该方法可行有效;土压力合力大小相等,但合力作用点与土压力分布存在明显差别;研究成果可为相关工程提供参考。
