TL;DR: Wen et al. as mentioned in this paper employed the tunnel earthquake disaster investigation to analyze and summarize the tunnel seismic damage on the basis of Wenchuan earthquake, and showed that the typical seismic damage of tunnels is lining cracking, collapsing, dislocation, construction joints cracking, and uplifting of invert, and usually lining cracking and collapsing account for a larger proportion.

TL;DR: The FBG sensors-based in situ monitoring technology can be well applied in the loess tunnel structure safety assessment and results indicate that the safety factors of various liner sections all meet the code requirements, which verify the safety and stability of the tunnel liner structure.

TL;DR: In this article, the authors analyzed the impact of vehicle load and train load on the structure of the shield tunnel of the metro line 2 and the Yongningmen tunnel by applying the three-dimensional (3D) dynamic finite element model.

TL;DR: A review of state-of-the-art work on mechanism, microstructure characteristic and physical mechanics mechanism of the seismic subsidence can be found in this paper, where the authors provide a comprehensive explanation, basics and earlier research performed on subsidence amount estimation and corresponding preventions of disasters have been presented briefly.

TL;DR: In this paper, the authors proposed a new damage model which can reflect the residual deviatoric stress after rock failure, and the reasonability of the new model was verified using the test results of the sandstone.
