摘　　要：结合青岛地铁一期工程3号线河河区间饱水砂层浅埋暗挖隧道施工实践,在总结饱水砂层超前小导管风压注浆施工技术基础上,自创饱水砂层风压注浆工法,围岩加固满足后续工序要求,防水堵水效果显著。In combination with the practice of shallow tunneling construction in water-saturated sand layer at river west station--river east station section of No. 3 line of Qingdao subway phase 1 project, based on summarizing the wind pressure grouting construction with advanced small pipe, the wind pressure grouting construction method for water-saturated sand layer is developed independently, the surrounding rock rein- forcement meets the downstream process requirements, and waterproofing and water plugging effects are remarkable.
