摘要
不同的施工方案对浅埋偏压连拱隧道结构、围岩的受力特征和稳定性有不同的影响,通过采用Midas GTS有限元软件对广东省某连拱隧道施工顺序进行数值模拟研究,重点研究施工方案对隧道沉降、中隔墙应力状态、围岩塑性区的影响。
Different construction schemes have different effects on the structure and stability of shallow buried multi-arch tunnel under unsymmetrical pressure and surrounding rock.In this paper, a study of different effects of construction sequence is carried out by analyzing a tunnel in Guangdong province using Midas GTS analysis software.The influence of the construction scheme on the tunnel settlement, the stress state of the middle partition,the plastic zone of the surrounding rock are studied emphatically.
