摘　　要：格形地下连续墙是悬臂式基坑支护结构的一种形式,由于其造价昂贵,一般仅用作大深度基坑的自立式围护结构。对部分采用格形地下连续墙围护的某船坞基坑格形地墙的实测水平变形进行了较为详细的分析,总结了格形地下连续墙围护结构水平变形的一些规律,指出了自立式格形地下连续墙变形计算存在的不足,提出了格形地下连续墙围护设计中仍需进一步研究的问题。The lattice concrete diaphragm wall is a type of cantilever supporting structure for foundation pits,and usually only be used in deep excavation because of high cost.The measured horizontal deformation is analyzed for a foundation pit of dock supported with lattice concrete diaphragm walls.Some deformation rules are generalized.At the same time,some problems of deformation calculation in practical projects and some topics to be studied on self-supporting lattice concrete diaphragm walls are proposed.
