| Abstract: | The construction of multi-arch tunnels in loess is complex and difficult. On the basis of the case of the first multi-arch tunnel in loess in China--Lishi Tunnel, the construction technology of it is discussed. The optimal construction scheme is determined by using the numerical simulation analysis. The key point in the construction is introduced in detail. The whole construction is monitored, and the monitoring data are analyzed. Then some conclusions on the construction technology are given. |
