Structure Design Characteristic of Jiangnanxi Air Defense Project/Zeng Chunliang, Xie Yike(The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010，China)
Abstract: The design characteristics of the structure of Jiangnanxi air defense project are introduced,and the design and construction measures of the project are presented. The performance conditions of uplift pile and anchor arm are evaluated. The results of the anchor arm withdrawal test are discussed,and it is concluded that anchor arm deformation less than 4mm can be a standard to decide whether the anchor arm can work normally. In addition, the methods of reverse construction in the project are recommended. The method have good society and economic performance.
Keywords: super-long concrete structure; against floatation design; reverse construction
