摘要
针对落差很大的大面积异型深基坑,采用多种围护组合方式,对13m深坑采用了在卸载条件下转换成2个坑套叠形式,减少了1道支撑的做法;对于27m超深坑和38m深的套管采用了特殊措施进行施工。在异型混凝土结构、空间曲面屋盖体系和新颖的曲面穿孔金属板夹层玻璃幕墙施工中探索了特殊的处理方法,为特殊造型的公共建筑施工积累了经验。
Several complex supporting were used in the light of great difference in elevation of large-scale irregularly shaped deep foundation pit. For 13m deep' s, two pit telescopiform were changed under unloading condition so as to reduce a row of supporting; for 27m super deep pit and 38m deep casing pile, special construction technique is used. Special treatments are probed in the construction of space curve roof system and novel laminated curtain wall with curve drilled-metal plate. The wealth of experience has accumulated for the construction of special-shaped public buildings.
