摘　　要：基于渗流-应力耦合分析理论模拟偏压连拱隧道开挖过程,分析连拱隧道在偏压条件下围岩位移变形特性及稳定性的影响,给出偏压连拱隧道施工过程中左洞上台阶与中隔墙连接处、以及右洞拱腰处为相对薄弱位置并有针对性地进行处治。Based on the seepage-stress coupling analysis theory, the excavation process of twin-arch tunnel under unsymmetrical pressure is simulated, and the influence of surrounding rock deformation and stability is analyzed, it is pointed out that the upper step of the left tunnel and the middle partition wall and the arch waist of the right tunnel are relatively weak positions during the construction of the double-arch tunnel with unsymmetrical pressure.
