摘要
Abstract
Soil mechanics-based theoretical calculation,numerical simulation,and engineering practice are combined to determine key factors such as slurry ratio,the height of guide wall and the stability of trench wall in the formation of concrete diaphragm wall,complete with the key points related to the trenching control of concrete diaphragm wall.By analyzing the construction of ultra-deep concrete diaphragm of a suspended curtain based on a highly permeable sand layer near river,some countermeasures to the collapse occurred during the construction are proposed.The trenching control points help shorten the construction period.The spatial truss support for ultra-deep concrete diaphragm wall applies to the welding and hoisting of steel cages,which improves the construction efficiency,lowers costs and man-hours.The study on new type of waterstop components for the joints of concrete diaphragm wall will avoid water seepage of the joints during the construction.关键词
