土钉墙+预应力锚杆支护技术在温泉大酒店工程中的应用

Application of combination of soil nailed wall and prestressed bolting bracing technology to the engineering of Wenquan Hotel

通过对土质参数、基坑挖深、周边环境和土钉墙、预应力锚杆的分析；采用边坡整体稳定、土钉整体抗拔、外部稳定性抗滑计算公式进行安全系数验算；并在施工环节采取一些有效措施，在施工过程中加强检测和监测工作，使得土钉墙＋ 预应力锚杆这一支护技术在深基坑工程中得以较好应用。

By analysis of soil parameter, deep foundation pit, sourroundings, soil nailed wall and prestressed boilting, using overall sidewall stability, overall soil nailing antipulling, external stability and antislip formula for safty coefficient calculation check as well as taking some effective measures in the construction and strengthening examination and supervision in construction process, to gain the better application of th combination of soil nailed well and prestrebolting bracing technology to the deep foundation pit engineering.
