摘要
在输水隧洞盾构施工过程中,将同步注浆层作为减震层可以加快施工进度,减少工程投入,具有重要的经济意义和技术价值。此次研究以具体工程为背景,利用数值模拟方式,探讨盾构施工输水隧洞同步注浆层刚度对隧洞抗震性的影响。结果显示,在盾构工程设计施工过程中,减小同步注浆减震层刚度可以有效提升输水隧洞抗震性。
In the process of tunnel shield construction,using synchronous grouting layer as damping layer can speed up construction progress and reduce project investment,which has important economic significance and technical value.In this study,the influence of the stiffness of synchronous grouting layer on the seismic resistance of the tunnel under shield construction is discussed by numerical simulation.The results show that reducing the stiffness of the damping layer can effectively improve the seismic resistance of the tunnel during the design and construction of shield engineering.
