| 中文摘要:介绍了北京创世纪大厦工程的场区工程地质条件、基坑边坡支护设计和支护施工工艺。该工程基坑属深大基坑，基坑周边场地狭窄，经计算对比采用西侧临路部分及临原有建筑部分上部砌挡土墙下部护坡桩加锚杆支护体系，其它部位选取上部土钉墙支护下部护坡桩加锚杆支护体系支护方案,很好地解决了采用纯土钉墙基坑安全可靠性不高的问题，又相对降低了整个基坑支护造价。 |

| Abstract:The engineering geological condition, pit support design and its construction process in Beijing Century Building Project are mainly introduced in this article. It is narrow around the deep and big pit. It is designed via calculation and contrast that the top wall with nail in soil plus the bottom slope-supporting pile is adopted on the narrow west pit near a road and existing buildings and that the top wall with nail in soil plus the bottom slope-supporting pile and anchor is used on the rest parts of the pit. This scheme has excellently solved the problem of the low security and has relatively reduced the cost of the support and protection of the pit. This article has some reference sense to the design and construction of the deep and big pit. |
