Special Issue Information

Dear Colleagues,

Currently, fast urban development has led to numerous tunnel and underground engineering (TUE) projects that are used for public or commercial purposes, and ensuring their structural health holds great significance for social stability. Owing to the coupling action of frequent external disturbances and intricate environments, behavioral deterioration occurs in these structures during long-term operation, leading to potential safety hazards. Therefore, the structural health monitoring (SHM) of TUE plays an essential role in the construction of smart and resilient cities. Specifically, SHM can help evaluate and predict the structural performance state of TUE and provide support in decision making regarding their maintenance to reduce the risk of failure and improve their structural resilience.

However, the complex operating environment and exorbitant monitoring costs result in fresh challenges for the SHM of TUE. This Special Issue, which aims to systematically show the cutting-edge achievements associated with the SHM of TUE, is thus established. All original papers on this topic are welcome, and comprehensive review articles are especially encouraged. The topics of interest include, but are not limited to, the following:

  • Case studies of the SHM of TUE;
  • New sensing technologies, data-processing methods, and monitoring solutions for the SHM of TUE;
  • New evaluation approaches and prediction models for determining the structural performance of TUE;
  • The development of secure intelligent control platforms and techniques for TUE and its applications;
  • Methods of resilience assessment for TUE under single and multiple disasters;
  • The application of artificial intelligence and machine learning techniques in the SHM of TUE.

With the increase in the number of buildings along the subway, the impact of building construction on the adjacent subway tunnels has gradually come to the forefront and become an important problem to be solved in the engineering field. In particular, the excavation and unloading process of deep foundation pits will trigger an additional deformation of the subway structure, which may pose a serious threat to the safety and stability of subway tunnels. This article is based on a foundation pit project in the sub-center of Beijing, focusing on the form of a connected double foundation pit. Using the HSS constitutive model for soil materials, this study simulates the deformation response of adjacent existing subway tunnels under three excavation sequences: sequential excavation, simultaneous excavation, and the comprehensive excavation of the connected double foundation pits. The study shows that, from the point of view of the total displacement of the whole construction process, the impact of a synchronized excavation of double pits on the existing tunnel line is relatively large in the process, and the impact of sequential excavation is relatively small in the construction cycle. The result of the similarity of the excavation sequence is the similarity of the impact trend. The volume of excavated earth determines the value of displacement change for each excavation scenario in each working condition and is also responsible for the convergence of changes. The trend of total tunnel displacement is more consistent with that of vertical displacement, which is dominated by vertical displacement, with horizontal displacement having a relatively small influence. The maximum value of the total tunnel displacement occurs at the side of the tunnel near the excavation area, and the direction is inclined to the excavation area. The application of supporting structures, especially the center plate and the bottom plate, can suppress the vertical deformation of the tunnel bulge. Full article
