摘要
深圳地铁多条运营线路位于填海区,为此以该区域的盾构隧道工程案例为基础,结合实际调查和数值计算分析,总结隧道异常变形规律,并根据限界设计和未来加固考虑,提出填海区单洞单线盾构隧道的合理内径,研究成果已在深圳市轨道交通四期工程中推广应用。
Based on the shield tunnel engineering study cases of Shenzhen metro lines located in reclamation area,taking into consideration of the actual investigation and numerical calculation analysis,this paper summarizes the abnormal deformation pattern of the tunnel.Based on the gauge design and future reinforcement consideration,it recommends the reasonable inner diameter of single tunnel single track shield tunnel in reclamation area.The research results have been widely used in the fourth phase project of Shenzhen rail transit.
