摘　　要：基于可靠性原理 ,建立了闸门面板可靠度分析的极限状态方程。利用统计分析所得的数据 ,对影响闸门面板可靠度的荷载及抗力统计数据进行了分析计算 ,得到其统计参数。然后采用JC法对《水利水电工程钢闸门设计规范》中闸门面板的可靠度进行了校准计算和分析。结果表明 ,闸门面板的可靠指标满足一级建筑物的安全水准 ,并且大于闸门主梁的目标可靠指标。同时提出了水工钢闸门面板结构设计的目标可靠指标取值建议。Based on reliability theory,a limit state equation for gate faceplate reliability analysis was founded. The loads and resistances statistical data affecting gate faceplate reliability analysis was calculated and analyzed using the statistical data obtained,and their statistical parameters was gained.Then, employing JC method the gate faceplate reliability in Hydraulic and hydroelectric engineering specification for design of steel gate was calibrated and analyzed.The calculated results indicate that the reliability indexes of gate faceplate meet safety levels of class I structures and are higher than that of gate main beams.Meanwhile the values of target reliability inde xes of hydraulic gate faceplate design are proposed
