Abstract: With the continuous development and utilization of urban underground space, new urban tunnels will inevitably affect the formation of nearby existing structures. Methods to minimize the environmental impact induced by adjacent construction have been a hot topic of research in recent years. Based on different cases of adjacent construction to the existing tunnels in Shanghai, many different...
Abstract: With the rapid development of urbanization in China, a large amount of metro constructions have been carried out in recent years. Dozens of shield TBMs driving simultaneously in the downtown area has raised up challenges for more efficient construction management. The lack of timely information communication and cooperation between all the participants involved in the project, especially the...
Abstract: The tunnel deformation monitoring methodology based on 3D LiDAR (Light Detection and Ranging) data shows broad application prospects in recent years due to the high- quality of acquired massive data. The proposed methodology provides a clear processing flow and comprehensive analysis result with adequate accuracy mainly by three parts: data acquisition, data processing and result analysis....
Abstract: One of the distinctive features of the subsea tunnel is the unlimited water supply. Groundwater seepage caused by subsea tunnel excavation brings two problems: one is the determination of water load of structure, the other is the prediction of water inflow. The complex geological structure of the gulf or strait has great influence on the groundwater seepage in the tunnel. Taking the NO.1 line...
