Seismic response of mountain tunnel induced by fault slip [PDF]

Scientific Reports
With the rapid development of Chinese transportation networks, such as the Sichuan-Tibet railway, numerous tunnels are under construction or planned in mountainous regions. Some of these tunnels must traverse or be situated near active fault zones, which

Real-time prediction of earthquake potential damage: A case study for the January 8, 2022 MS 6.9 Menyuan earthquake in Qinghai, China

Earthquake Research Advances, 2023
It is critical to determine whether a site has potential damage in real-time after an earthquake occurs, which is a challenge in earthquake disaster reduction. Here, we propose a real-time Earthquake Potential Damage predictor (EPDor) based on predicting

Dynamic evolution of crustal horizontal deformation before the Ms6.4 Menyuan earthquake

Geodesy and Geodynamics, 2016
An Ms6.4 earthquake occurred in the Menyuan county of Qinghai Province on Jan 21, 2016. In order to recognize the development of horizontal deformation and distinguish precursory deformation anomalies, we obtained coordinates time series, velocity and ...

Shaking table test and cumulative deformation evaluation analysis of a tunnel across the hauling sliding surface

Deep Underground Science and Engineering, Volume 2, Issue 4, Page 371-393, December 2023., 2023
The shaking table test of a tunnel crossing the hauling sliding surface is carried out. The MIa evaluation index considering the natural frequency characteristics of earthquakes is proposed. The plastic effect coefficient evaluation index considering the plastic effect of the lining under an earthquake is proposed.

Seismic Behavior of Qinghai‐Tibetan Railway Embankment in Permafrost Regions: A Case Study

Shock and Vibration, Volume 2023, Issue 1, 2023., 2023
The temperature is a critical factor that determines the unfrozen water content and ice content in the frozen soil. In view of mechanical properties of the frozen soil depend on the volume of components of the four‐phase systems, thus the temperature has a significant impact on the mechanical behaviors and deformation properties.

A Complete Map of Fine‐Scale Slip Rate Distribution and Earthquake Potential Along the Haiyuan Fault System

Geophysical Research Letters, Volume 49, Issue 24, 28 December 2022., 2022
Abstract We use Sentinel‐1 Interferometric Synthetic Aperture Radar observations to derive the first complete map of slip‐rate distribution at km‐scale along the 1,000‐km‐long Haiyuan fault system, and further to analyze its earthquake potential. Rate distribution reveals four highly locked asperities (slip rate <1 mm/yr) and three creeping regions ...
