阐述了某大型深基坑边坡喷锚支护的设计方案及施工方法。从喷锚支护结构设计、土层物理力学性质、施工工艺、现场管理、技术经济评价等方面,进行了分析、讨论。指出该技术具有及时、快速、随挖随支,与基坑开挖同步进行,不占独立工期,占用施工场地小,边壁位移量小等特点,可供同类专业参考。 The design scheme and construction method of shotcrete and bolt supporting for a large deep foundation pit slope are expounded. From the spray anchor structure design, physical and mechanical properties of soil, construction technology, site management, technical and economic evaluation, etc., were analyzed and discussed. It is pointed out that this technology has the characteristics of timely, fast, with digging support, synchronizing with excavation, not occupying independent construction period, occupying small construction site and small displacement of side wall.
