摘要
试验表明钢闸门的面板在进入弹塑性阶段后，仍有很大的强度储备。根据板壳理论及结构塑性极限分析定理，分别推出了钢闸门面板的弹性极限承载力及塑性极限承载力，从而给出了钢闸门面板设计公式中的弹塑性调整系数的理论值，供修订规范参考。
Experiment shows that a steel gate plate has a large strength stock after it reaches the elastoplastic phase.According to the shellslab theory and the theorem of plastic limit analysis of structure,the authors have derived the proof bearing capacity and the plastic ultimate bearing capacity of steel gate plates.Thus,the theoretical value of elastsplaslic adjusting coefficients for the design formulae of steel gate plates is given,which provide every country a reference for revising standards.
