中文摘要：
利用蒙特卡洛方法分析了影响方块、扶壁和重力沉箱式码头抗滑、抗倾稳定性可靠指标计算中作用效应与抗力变异性的主要因素,通过对蒙特卡洛模拟结果的回归分析,建立了重力式码头抗滑、抗倾稳定性可靠指标计算中作用效应与抗力变异系数与这些变量的关系,最后利用JC法计算的可靠指标进行校正,提出了方块、扶壁和沉箱式重力码头抗滑、抗倾稳定性可靠指标的简化计算公式。与分项系数法相比,在计算量增加不大的情况下,利用简化公式可求得重力式码头的抗滑、抗倾稳定性可靠指标。
英文摘要：
The main variables affecting the variability of action effects and resistances in the computation of reliability index of the stability of gravity quay are analyzed using the Monte-Carlo method.The relationship between those variables and the coefficient of variability of the action effects and resistances is established based on the regression analysis to the analog results.The simplified formula calculating the reliability index of the resistance to sliding and overturning is put forward after the calibration according to the results calculated by JC methods.The reliability index of the resistance of sliding and overturning for gravity quay walls can be work out by the simplified methods with nearly the same amount of calculation as the partial coefficient method.
