| 摘 要： | 以104国道界河加筋土挡土墙失稳实例,在对路面与挡土墙相互作用机理分析的基础上,运用数值模拟方法,对车辆荷载下、不同质量的路面对挡土墙稳定性的影响进行分析. 结果表明:路面强度对挡土墙稳定性和变形具有非常敏感的影响;且挡墙越矮,影响越大.

| Abstract: | According to a reinforced earth retaining wall failure instance of No.104 National Road in Shandong Province of China,the effect of pavement quality on the stability of a retaining wall under automobile loading was analyzed by numerical simulation method on the basis of analyzing the interaction mechanism between pavement and retaining wall.The result shows that pavement strength can sensitively affect the whole stability and part deformation of the reinforced earth retaining wall.The lower the retaining wall,the more sensitive the effect is. |
