结合深圳地铁5号线灵芝—洪浪站区间暗挖地铁隧道工程的复杂地质条件及施工条件,通过对大量地层变形实测数据的分析,深入研究复杂地质条件下地层沉降变形的规律。研究结果表明,隧道开挖后,增大支护刚度并及时封闭成环,可以有效控制地层变形,满足了施工允许的沉降要求,可为类似工程提供相关的技术参考资料。
Combined with the complex geological conditions and construction conditions of the underground excavation metro tunnel project of Ganoderma lucidum-Honglang Station in Shenzhen Metro Line 5, through the analysis of a large number of measured data of formation deformation, the law of formation settlement under complex geological conditions is deeply studied. The results show that after the excavation of the tunnel, the support stiffness is increased and the ring is closed in time, which can effectively control the formation deformation and meet the requirement of settlement for construction. It can provide relevant technical reference materials for similar projects.
