地下连续墙作为一种较新型的结构形式,在众多特定的工程环境中表现出了不可替代的优越性。由于施工技术水平的提高和设计理论的发展、完善,地下连续墙以其独有的特点,越来越得到了工程界的重视。随着今后人类对地下空间的不断拓展,地下连续墙必将会得到更广泛的应用。本文就上海宝山钢铁(集团)公司三期1580mm热轧工程铁皮沟及漩流沉淀池地下连续墙的设计实践进行总结,并介绍笔者对地下连续墙的认识和体会。 Underground continuous wall, as a relatively new type of structure, has shown irreplaceable superiority in many specific engineering environments. Due to the improvement of construction technology and the development and improvement of design theory, the underground continuous wall has received increasing attention from the engineering community because of its unique features. With the constant expansion of underground space by mankind in the future, underground continuous walls will surely find wider application. This paper summarizes the design practice of the Tiepigou and swirling sedimentation tank underground continuous wall in Shanghai Baoshan Iron and Steel (Group) Corporation’s third phase of the 1580mm hot rolling project, and introduces the author’s understanding and experience of the underground continuous wall.
