摘要
以一座向家坝库区码头的加筋岸坡稳定性为研究对象,根据简化Bishop理论,建立了加筋岸坡的稳定性极限状态函数,并采用Monte Carlo模拟法对土体密度ρ、抗剪强度c和φ值、加筋材料强度及水位等参数进行随机抽样和岸坡的可靠度分析,最后分析了土体抗剪强度c、φ值的相关系数对岸坡安全系数均值和可靠度指标的影响,得出了一些有益的结论。
The reinforced slope stability of a wharf in Xiangjiaba reservoir was taken for research.Based onsimplified Bishop theory, the reinforced slope stability limit state function was build, and the Monte Carlo simulation was used in soil density p, shear strengthc、φ reinforced material strength and water parameters such as random sampling and reliability analysis of slope.Finally, the influence analysis of values of the mean slope safety factor and reliability index by the soil c、φ affect the correlation coefficient was done, which obtained some useful conclusions.
