摘要
通过对某船闸加固前后闸室结构的有限元开裂分析，研究了裂缝产生的原因和加固措施的效果．研究表明：裂缝主要是由于闸室底板拉应力过大及缝面处理质量问题引起的；所采取的加固措施能提高闸室墙的稳定性，但还应作进一步研究．
In this paper,with FEM analysis of a lock bay structure before and after reinforcement,the cause of cracking and the effect of reinforcement are studied.The research indicates that cracks are caused by the large tensile stress and construction defaults,and all the reinforcement may enhance the stability of the bay wall,further study is still needed.
