Numerical simulation of pavement quality affecting the stability of a retaining wall

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.
