摘　　要：针对软土地区上锚下撑船闸闸室变形较大的缺陷 ,通过对典型实例的有限元分析 ,并借鉴建筑基坑相关经验 ,研究了影响软土地区上锚下撑船闸闸室墙水平位移的设计因素和施工因素 .研究结果表明 ,采用被动土体加固、增大墙体刚度等方法可控制闸室墙变形 .In consideration of the large deformation of up-anchored and down-supported ship lock chambers on soft soil foundation, based on finite element analysis of a typical project and related experiences in construction of foundation pits, some design and construction factors influencing the horizontal displacement of ship lock chambers are studied. The results show that measures, such as passive soil reinforcement and increase of rigidity of lock walls, can prevent deformation of lock walls.
