摘要
为解决锚杆(索)超红线问题,考虑主楼的节点工期要求,特房筼筜·温莎公馆基坑工程采用以下多种支护形式:半逆作法、悬臂桩支护、桩撑支护、桩锚支护等,本文介绍了设计思路及监测结果。随着各地区限制锚杆(索)超红线文件的出台,这可以为解决锚杆(索)超红线问题提供一些启发。
To resolve the problem of soil nail / tieback beyond the red line,considering the requirement of node construction in main building,the excavation of Tefang Yundang Wensha Mansion adopted the following forms of support: semi top- down method,cantilever pile support,pile brace support and pile anchor support. This paper introduces the design thoughts and monitoring results. The monitoring results show that using semi top- down method can satisfy the allowable design limits,which provide insights to resolve soil nail / tieback beyond the red line.
