Abstract: A dense network of underground tunnels usually makes subsequent tunnels cross existing tunnels in the process of urbanization. In this study, we mainly study the deformation of the subway line 11 caused by the under-crossing of the Qianhai–Nanshan Integrated Drainage Deep Tunnel in Shenzhen. We analyzed the process of displacement during the subsequent tunnel under-crossing the subway line 11 according to the displacement monitoring data. Our results demonstrate that deformation detection is an effective measure for controlling the impact of the subsequent tunnel under-crossing subway tunnels. The aim of this paper may provide guidelines for some existing tunnels that are under-crossed by subsequent tunnels with similar conditions.
