摘要
对于某些超深基坑,若仅仅采用某种单一的支护形式,在安全性及经济性方面往往无法达到较佳的效果,而若要在安全性及经济性方面找到一个相对合理的平衡点,则往往需要采用多种支护形式结合的复合支护方案方可实现。本文介绍了土钉墙与逆作拱墙复合支护体系在某超深锚碇基坑中的成功应用,并简要分析了该复合支护方案的设计计算,对某些超深基坑工程设计采用类似复合支护方案,具有一定的借鉴意义。
The effects in security and economy are unfavorable to some extra deep foundation pits which were sup- ported with single measure. Actually, in order to achieve a reasonable equilibrium point of security and economy in deep foundation pit supporting project, the various support forms are used together. This article introduces the successful appli- cation of the compound supporting system of soil nailing and arch wall in an extra deep foundation pit. The design calcu- lation of scheme is analyzed in brief. The article gives some references and suggestions for the similar foundation pits.
