摘　　要：根据最新导出的荷载变量相关时结构可靠指标β的Hasofer Lind计算方法,利用特定地点的长期波浪观测资料,对明、暗基床的削角直立式防波堤进行了可靠度分析,得出了可靠指标β与传统设计方法中安全系数K的关系曲线,进而给出了削角直立堤抗滑移和抗倾覆极限状态下各项分项系数的建议值。Based on Hasofer-Lind method for determining the reliability index β of structures with correlated loads, and by utilizing the long-term observed wave data at a given place, the reliability of the chamfered vertical breakwaters with low or high rubble mound foundations is analyzed. The relation curve between reliability index β and safety factor K in the traditional design method is obtained. And the proposed values of different partial coefficients for chamfered breakwaters in limited states of anti-sliding and anti-overturning are given.
