摘　　要：深圳地铁四号线上民区间为富水流砂地层,隧道下穿立交桥群及多条燃气管线,隧道施工难度大,风险高。重点研究了不同隧道围岩变形控制技术对隧道稳定性的影响及适用性分析,通过数值模拟、现场试验等研究手段对不同隧道围岩变形控制技术从围岩变形控制可靠性、技术可行性、经济合理性和工程时间性等方面进行综合对比分析,得出了富水流砂地层合理的隧道围岩变形控制技术。研究结果对国内同类施工条件下的工程施工具有一定的借鉴意义。The tunnel between cross section mileage k9＋125 and k9＋255 at Shangmeilin-Mingle Section of Shenzhen Subway Line 4 is located in rich-water and shifting-sand strata and underpasses flyover bridges and multiple under ground pipelines.The tunnel construction faces big difficulty and high risk.A study on the effects of different tunnel surrounding rock deformation control technologies to tunnel stability and feasibility analysis is carried out with numerical simulation and field experiment methods etc.Surrounding rock deformation control reliability,technical feasibility,economic rationality and construction timeliness are considered in this study comprehensively.The most reasonable surrounding rock deformation control technology under the condition of rich-water and shifting-sand strata is obtained.This study can be an useful reference to other underground projects under similar construction conditions.
