| Abstract: | Monitoring becomes especially important due to the shortage of construction and design experience for four-lane twin tunnels with small clear-spacing. Based on the monitoring data, this paper discusses the important application value of in -situ monitoring; putting forward design optimization according to the project features; analyzing the typical data of slope settlements and crown subsidence for the feedback to design and construction; advancing early-warning displacements for the project of large profil... |
