【Abstract】 The pulling and arching supporting structure in deep foundation pit is used widely in many deep foundation pit projects due to its economy,reliability, high speed and simplicity. Based on the characters of the engineering geological condition and surrounding of the concrete project, this paper describes the pulling and arching supporting structure, the design scheme and construction techniques in a detailed way. The project practice indicates the design scheme is feasible and economical, and the pulling and arching supporting structure can offer its particular advantage in many large-area deep foundation pit projects, especially under the conditions of narrow-spaced field and poor surrounding.更多还原
