Design and Application of Integral Technique for Basement"s Top-down Construction/Luo Chiyu, Chen Xing (The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010, China)Abstract:To solve the critical problems of complicacy in technique and difficulty in application during the practice of the basements topdown construction, the conception of the integral technique for basement"s top-down construction is put forward. The path, principle and design method of sticking points in the integral technique are also presented. Based on the experience of the application of top-down method in some projects, the character of new techniques integrated in design and construction as well as economic benefit is analyzed, which can be referred for future top-down construction.
