结合具体工程,对暴雨条件下自嵌式加筋挡土墙存在的变形、受力特征和稳定性进行了有限元数值模拟,并与一般气候条件下进行对比。结果表明:在暴雨条件下,墙体将产生较大的侧向变形;墙背土压力在加筋处明显增大;挡土墙内部筋材之间局部出现拉应力区,筋材断裂后拉应力区明显扩大,存在墙面倾覆的趋势。该结论在对特大暴雨后加筋挡土墙局部破坏事故的现场调查后得到了验证。 Combined with specific engineering, finite element numerical simulation of the deformation, force characteristics and stability of the self-retaining reinforced retaining wall under rainstorm condition is carried out and compared with the general climatic conditions. The results show that under heavy rain conditions, the wall will produce large lateral deformation; the earth pressure on the back of the wall increases significantly at the stiffened zone; and the tensile stress zone appears locally between the stiffened walls of the retaining wall, The stress area is obviously enlarged, and there is a tendency of wall tipping. This conclusion has been verified after an on-the-spot investigation of the local failure of reinforced earth retaining walls after heavy rainfall.
