| 摘 要： | 研究了有波浪力情况下重力式码头的抗滑、抗倾稳定性抗力和荷载效应的统计特征,提出了抗滑、抗倾稳定性可靠指标的简化计算公式,根据10个方块码头和46个沉箱码头的JC法可靠指标计算结果确定了简化计算公式和简化设计公式的参数。研究表明,波浪力占总荷载效应的比例对可靠指标的计算结果影响很大;对于同种类型的重力式码头,在相同的墙后填料情况下,抗滑、抗倾稳定性计算中抗力和荷载效应的均值系数和变异系数可视为常数;采用简化公式计算的重力式码头抗滑、抗倾稳定性可靠指标与JC法的计算结果非常接近。

| Abstract: | The statistical characteristics of load and resistance of gravity quay against sliding and overturning with wave force are investigated.And simplified expressions in which the parameters are determined based on the reliability outcome of 10 block quays and 46 caisson quays using JC method are proposed.It indicates that the wave force has a strong influence on reliability of the gravity quay.In the case of same type of gravity quay and same back filler,the bias and variation coefficients of the load and resistance for sliding and overturning can be regarded as constants.The results of reliability index obtained by simplified expressions are very close to the results obtained by JC method. |
