摘　　要：深基坑拉锚式支护结构由于其经济可靠而且施工快速简便 ,已经在许多深基坑工程得到了迅速推广应用。结合工程实例 ,通过分析工程场地周边环境与工程地质条件 ,经方案比较后 ,采用拉锚式支护方案 ,着重阐述了拉锚式支护方案设计与施工工艺。工程实践表明 ,该设计方案是可行且经济的 ,对场地狭小、周边环境复杂的大面积深基坑工程 ,拉锚式支护体系具有独特的优势。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.
