地连墙欧洲规范( Diaphragm wall EN 1538 )

地连墙欧洲规范EN1538简介

EN1538是欧洲标准化组织（CEN）发布的关于“地连墙”（DiaphragmWall）施工的技术规范标准，全称为《执行地下连续墙施工的专用工作规范》（*Executionofspecialgeotechnicalworks–Diaphragmwalls*）。该标准为设计与施工单位提供了在欧洲范围内通用的地连墙施工技术要求和指导原则，适用于建筑、桥梁、隧道及地下工程中使用的地连墙结构。

EN1538标准涵盖了地连墙施工的全过程，包括墙体设计基本原则、槽段开挖、泥浆护壁、钢筋笼制作与吊装、混凝土浇筑、质量控制与检测等内容。标准强调了施工过程中对环境的影响控制、安全措施以及材料性能的要求，旨在确保地连墙在承载力、止水性和耐久性方面的可靠性。
