摘要
单洞双层隧道充分利用地下空间,能有效降低土地占用率并提高交通使用率。文章结合实际工程案例,对单洞双层暗挖隧道衬砌的力学性能进行分析和验证。研究结果表明,当混凝土强度一定时,随着衬砌厚度增大,位移量逐渐减小且减小幅度逐渐变小;当衬砌厚度一定时,随着混凝土强度等级的提升,衬砌最大轴力与最小轴力均呈现下降趋势,分别降低15.76%与13.71%。
The single-hole double-layer tunnel can effectively reduce the land occupation rate and improve the traffic utilization rate by making full use of underground space.Combined with the actual engineering case,this paper analyzes and verifies the mechanical properties of lining in single-hole double-layer bored tunnel.The results show that when the concrete strength is constant,with the increase of lining thickness,the displacement decreases gradually and the reduction range decreases gradually;when the lining thickness is constant,with the increase of concrete strength grade,the maximum axial force and the minimum axial force of the lining both show a downward trend,which are reduced by 15.76%and 13.71%respectively.
