本文结合工程实例,依据国内外有关文献资料,采用统计分析及误差筛选法,对深层地下连续墙设计施工中关于施工单元长度的确定、混凝土保护层厚度、导墙形式、预埋件与孔洞的留设、墙体施工精度、墙与底板的连接、工程事故分析等问题进行了系统分析研究,具有一定的实用价值,可供从事深层地下连续墙设计施工的工程技术人员参考。 In this paper, based on the engineering examples, based on the relevant literature at home and abroad, using statistical analysis and error screening method, the design and construction of deep underground continuous wall on the construction unit length determination, concrete cover thickness, guide wall form, embedded parts and holes Leaving a wall, the construction accuracy of the wall, the connection between the wall and the floor, engineering accident analysis and other issues were systematically analyzed and studied, which has a certain practical value for engineering and technical personnel engaged in the design and construction of deep underground continuous wall reference.
