大型标志性超高层建筑结构及施工关键技术:广西九洲国际大厦
$62.07
《大型标志性超高层建筑结构及施工关键技术》一书以广西九洲国际大厦超高层项目为研究对象,结合项目实践,研究了基于混凝土框筒结构体系的超高层建筑设计与施工技术,从超高层地基基础、混凝土结构超限核心技术、施工组织管理等方面进行了较为系统的探讨。
本书对广西九洲国际大厦的钢管混凝土柱RC环梁、框筒钢管剪力墙等创新设计进行了介绍,并对组合结构关键技术、主体结构抗震分析进行了研究,详细总结了与超高层超大直径人工挖孔桩承载力有关的设计关键。结合施工中的数据模拟与监测分析,对该结构在各个工况下的变形监测情况进行深入研究,总结出超高层建筑徐变随施工工况和时间的变化规律。
本书还对超高层结构施工的关键技术进行了探讨和总结,如详细探讨了垂直运输内爬式塔吊施工技术、内爬式塔吊高空拆塔施工技术及高大模板支撑体系的设计及施工,并开发了承插型套扣式钢管脚手架设计软件。此外本书还探讨了高强高性能混凝土配合比设计及质量控制关键技术、高强高性能混凝土泵送关键技术。本工程地基基础采用多种支护形式,对超深基坑设计数值方案进行了模拟,并结合施工期间长期监测数据分析,研究了超深基坑支护设计和安全施工技术。
广西九洲国际大厦超高层项目,把钢管混凝土环梁技术应用到超300m 的现浇混凝土框筒结构体系中,是一次创新与尝试。在施工中成功解决了结构体系带来的技术难题和降效问题,总结的上、中、下三册研发成果在同类超高层工程施工中具有较大的参考价值和指导意义。
本书可作为超高层建筑施工及设计人员的参考用书,也可作为高校教师教研资料。
