摘　　要：针对淤泥质粉质粘土层格型地连墙施工过程中槽壁易发生坍塌,成槽困难;淤泥质粉质粘土层粘聚力、内摩擦角小,土体不稳定,在地连墙成型后土方开挖阶段,土体侧压力大,含水率高,而在地连墙接头处对力学性能、防水性能要求高从而形成技术难点,结合富水富池船闸工程格型地连墙基础,分析了该地连墙的槽段优化、槽壁加固处理、双十字型钢板接头的优化措施与应用。In response to the fact that the slot wall is prone to collapse during the construction of a grid type diaphragm wall in a muddy and silty clay layer,Difficulty in slotting;The cohesive force and internal friction angle of the muddy silty clay layer are small,Unstable soil mass,Earth excavation stage after the formation of the diaphragm wall,High lateral pressure of soil,High moisture content,However,the high requirements for mechanical and waterproof performance at the joint of the ground connecting wall create technical difficulties,Combined with the grid connected wall foundation of the Fushui Fuchi Shiplock project,Analyze the optimization measures and applications of the groove section of the connecting wall,reinforcement treatment of the groove wall,and optimization of the double cross shaped steel plate joint in the area.

关 键 词：格型地连墙 槽段优化 槽壁加固处理
