    Abstract:

    In a foundation pit supporting engineering of Zhenzhou, the pile-anchor support, micro-pile + pre-stressed anchor composite soil nailing wall support and micro-pile composite soil nailing wall support systems are adopted respectively. The paper introduces the design and construction schemes of slope retaining pile, pre-stressed anchor cable, micro pile, pre-stressed anchor, soil nailing wall and perforated pipe pile in detail, as well as the emergency response plan adopted for the abnormity in foundation pit deformation monitoring, this technical achievement provides reference for the design and construction of similar projects.
