摘　　要：结合深圳地铁竖井的施工,详细阐述了水泥旋喷桩的施工工艺和施工监测.通过施工监测,在降水条件下,水泥旋喷桩既有效的阻滞了地铁竖井外地下水,保证了周边建筑物的安全,又充分利用水泥旋喷桩改良的基坑边坡土体,保证了竖井施工的安全.该技术对于特定地质条件下地铁竖井工程的施工,提供了有效的借鉴意义.Combined with the shaft of the Shenzhen Metro Construction, construction technology and construction monitoring of jet cement pile are presented in this paper. Through the construction monitoring under the conditions of precipitation, jet cement pile effectively both blocked the underground water outside the subway shaft, and ensured the safety of the surrounding buildings. Also it improved the pit slope soil, thus ensuring the safety of the shaft construction. The construction technology provided an effective reference for subway shaft project under the specific geological conditions.
