摘要
采用锚杆静压桩(硬托换)和灌浆加固(软托换)的综合托换技术,对紧邻开挖基坑边沉降未稳定的旧楼房基础进行加固处理,在基坑开挖中对边坡支护采取喷锚网技术,从而达到了不影响楼房使用、保证楼房安全和基坑开挖顺利进行的目的,其设计方法和施工技术对相关工程具有实际的参考价值。
The combined reinforced technology with static bolt-pile and grouting is adopted in the reinforcement for the old building with large settlement near foundation pit, and the soil nail wall is applied to support the slope while excavating. The presented methods of design and construction are of reference significance for other similar projects.
