摘要
城市地下大跨度多层重叠隧道在建设中会穿过或临近大量的既有构筑物,其破坏形态、荷载分布和隧道间的相互作用极为复杂。以重庆解放碑地下停车库及连接通道三期工程为研究背景,通过有限元法数值模拟并进行定性、定量分析,研究了螺旋隧道群施工对围岩和地表建筑物的影响;通过现场监测数据对比分析,确定了隧道群的展线方案和最优的开挖顺序和方法,并为类似工程提供借鉴指导。
The construction of urban underground long-span multi-storey overlapping tunnel will pass through or approach many existing structures,and its failure mode,load distribution and interaction between tunnels are very complex.Based on the project background of Chongqing Jiefangbei underground parking garage and connecting channel phase III,the impact of spiral tunnel group construction on surrounding rock and surface buildings was studied through finite element numerical simulation,qualitative and quantitative analysis method.Moreover,through the comparative analysis of on-site monitoring data,the alignment scheme of tunnel group and the optimal excavation sequence and excavation method were determined,which provided reference and guidance for similar projects.
