【Abstract】 The faceplate of a steel lock gate still has a large margin of safety after it has been in the elasto plastic phase.Based on the shell slab theory and the theory of elastic limit analysis,the elastic limit bearing capacity and the plastic limit bearing capacity of the faceplate of a steel lock gate are solved respectively.Then,the theoretical value of the elasto plastic adjustment coefficient for the design formula of steel faceplate is proposed,which may serve as a reference in the revision of related codes.更多还原
