摘要
本文以哈尔滨地铁三号线湘江路-会展中心区间地铁隧道暗挖段工程为背景,对大跨度变截面隧道和平行标准断面隧道施工进行数值模拟。考虑管廊为既有结构与新建结构两种情况,对不同截面的地表沉降规律进行研究,并将模拟结果与监测数据进行对比验证。结果表明管廊为新建结构时地表沉降整体大于管廊为既有结构时的沉降,且最大地表沉降更偏向于标准断面。
It takes the large section excavation of transit tunnel between Xiangjiang Road Station and Exhibition Center Station of Harbin Metro Line 3 as the background,simulating the construction of large-span variable cross-section tunnels and parallel standard cross-section tunnels.Considering the pipe gallery is an existing structure or a new structure,the ground settlements of different sections were studied and the simulation results were compared with the monitoring data.The results show that the ground settlement of the new pipe gallery is greater than that of the existing pipe gallery,and the maximum ground settlement is more inclined to the standard section.
