TL;DR: Wang et al. as discussed by the authors investigated the current problems of UUS development and utilization in China, and then analyzed the planning methods and general thoughts of overall underground space layout, which is conducive to the orderly development of urban space and alleviation of increasing human-land conflicts.
104 citations
TL;DR: In this article, an index system for UUS resource evaluation was put forward and its analytical process was based on the Geographic Information System (GIS) and some mathematical tools, such as the analytic hierarchy process (AHP), the most unfavorable grading method (MUGM) and the exclusive method (EM).

TL;DR: In this paper, the ground deformation during a pneumatic caisson construction in Shanghai soft ground was evaluated using a finite-element program, and the accuracy and reliability of the proposed model were verified.
Abstract: Characterized by unmanned excavation and remote controlling, the new pneumatic caisson (NPC) method has advantages in deep excavation such as deep shield tunnel shafts and some underground construction close to the existing structures or facilities. When adopted in urban areas, it is very important to control the ground deformation during a caisson construction. For this purpose, field measurements of ground deformation were conducted during a tunnel shaft construction in Shanghai soft ground, in which the NPC method was used. On the basis of the particular construction procedure of a pneumatic caisson, one kinematic mechanical model was proposed for evaluating the influence of NPC construction on the surrounding strata. This model was incorporated into a finite-element (FE) program. By comparing the FE-predicted results of the proposed model and the field measurements, the accuracy and reliability of this model were verified.

TL;DR: In this paper, the authors show that tunnel deformation is mainly due to urbanisation-induced land subsidence in Shanghai, and the magnitude of tunnel settlement is correlated to sublayer settlement rather than ground surface settlement.
452 citations
TL;DR: The results show that >50% of metro lines are highly exposed to flood risk, indicating that the Guangzhou metro system is vulnerable to flood events.

TL;DR: In this paper, the authors proposed a new longitudinal structural model to consider the shearing dislocation between rings, which can describe the actual deformation mode of a tunnel reasonably and compared with the traditional Euler-Bernoulli beam model based on a field measured longitudinal deformation of a Shanghai metro tunnel.
