依山而建高落差倾斜结构施工关键技术

Key Technologies of Inclined Structure with High Fall Depended on the Mountain

以贵阳花果园办公一号楼依山而建高落差倾斜结构建筑物为例,阐述了此类依山而建复杂工程中超厚大斜率剪力墙施工关键技术、自密实高性能混凝土斜钢柱施工技术、超厚钢筋混凝土剪力墙二次转角施工关键技术、大跨度超大截面钢板墙梁施工关键技术、依山倾斜超薄剪力墙施工关键技术、山地大直径微变形减振桩施工关键技术等。最终保证了复杂环境中依山而建倾斜结构在合理工期内的安全施工。

Taking the inclined structure with high fall depended on the mountain of Guiyang Huaguoyuan building No. 1 project as an example, a series of key technologies are described, including the key construction technology of shear walls with super-thick large slope, inclined steel columns technology by high performance self-compacting concrete, two times rotation technology of super-thick shear walls, key technology of steel plate beams with large-span and super-large section, key technology of super-thin shear walls depended on the mountain, construction of large diameter damping piles with small deformation. At the reasonable construction period, in the complicated environment, the construction safety of the inclined structure with high fall depended on the mountain is guaranteed finally.
