摘要
以南京秦淮新河格子桥上游右岸迎水坡为算例,进行护坡的稳定分析。利用极限平衡法和有限元强度折减法计算不同护坡比(1∶2,1∶3,1∶4)和有无铺设生态绿化混凝土等条件下护坡稳定安全系数,深入研究护坡的稳定性。同时,根据计算得到降雨入渗后护坡的水平向位移来探讨生态绿化混凝土对护坡稳定的影响。
Taking the slope of the right bank upstream of the new Qinhuai River Lattice Bridge in Nanjing as an example,the stability analysis of slope protection was carried out. Using the limit equilibrium method and the finite element strength reduction method to calculate different slope protection ratios( 1:2,1:3,1:4) and the slope stability safety factor under the conditions of presence or absence of longitudinal laying eco-greening concrete and other conditions,and the stability of slope protection was studied in depth. At the same time,the horizontal displacement of the slope after rainfall infiltration was obtained to explore the influence of eco-greening concrete on slope stability.
