摘要：Based on the deep excavation of Fengxihe Station of Chengdu Metro Line 17, the groundwater treatment plan for the deep sandy pebble stratum in Wenjiang district of Chengdu, the hole forming process of the retaining pile and the design of the retaining structure and the on-site monitoring data were analyzed and studied. Through systematic research on key technologies, the design and construction optimization schemes are proposed, and the relevant information of on-site information construction is enriched, which provides reference and reference for the design and construction of station excavations in similar strata.
