摘要
以四川省嘉陵江凤仪场船闸工程为例,采用空间三维实体有限元法,建立了船闸闸室结构的仿真力学模型,可以全面计算、分析闸室结构内力、位移以及稳定性、安全性等各项技术指标,为船闸结构设计提供了技术支持。同时,通过不同工况下的结构计算,不仅可对闸室结构进行优化设计,还可分析得到影响结构安全性、稳定性的关键因子。
Based on the Fengyichang ship lock project along the Jialing River in Sichuan province,we establish the mechanical simulation model of lock chamber structure by adopting the space 3D finite element method,to calculate and analyze the technical indices including the internal force,displacement stability,as well as the safety of the structure,etc.,so as to provide the technical support for the design of the lock structure.Meanwhile,according to the calculation results of the shiplock under different conditions,we may not only improve the lock＇s structure,but also get the key factor affecting the structural safety and stability of the ship lock.
