Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Evidence of transtensional deformation associated with neotectonics: Insights into the velocity structure and source mechanism of Nanga Parbat syntaxis, northwestern HimalayasKey points

Earthquake Science
A detailed understanding of seismicity originating from the Nanga Parbat syntaxis in the northwestern Himalaya is crucial for characterizing the active fault systems and associated neotectonic processes in the region.

Signal-based Bayesian Seismic Monitoring

CoRR, 2017
Detecting weak seismic events from noisy sensors is a difficult perceptual task. We formulate this task as Bayesian inference and propose a generative model of seismic events and signals across a network of spatially distributed stations. Our system, SIGVISA, is the first to directly model seismic waveforms, allowing it to incorporate a rich ...

Experimental Study on the Lateral Response of Large‐Scale Unbonded Steel‐Mesh‐Reinforced Rubber Bearings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional unbonded elastomeric bearings (ULNRs) are cost‐effective but prone to sliding during earthquakes due to their limited shear deformability. Unbonded Steel‐Mesh‐Reinforced Rubber Bearings (USRBs) offer a solution with increased deformation capacity.

Seismicity and seismic monitoring of Canada’s volcanic zones

Canadian Journal of Earth Sciences
Canada’s recently active volcanic zones (e.g., eruptions during the past 10 000 years) are all located along the tectonic plate boundary region of western Canada, extending for more than 2000 km from southern British Columbia to the Yukon/Alaska border. In this article, we describe the history of seismic monitoring in and near these volcanic zones and

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Coupled Assessment of Injection Pressure–Driven Risk, Trapping Evolution, and Cost Uncertainty in Geological CO2 Storage

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...

Score Reliability and Validity of a Mexican Dialect Spanish Translation of the Flourishing Scale With Mexican Earthquake Survivors

Journal of Counseling &Development, EarlyView.
ABSTRACT The Flourishing Scale (FS) scores have demonstrated acceptable psychometric properties in general adult populations, but no previous research has validated its use among natural disaster survivors. This study examined the reliability, validity, and measurement invariance of a Mexican dialect Spanish translation of the FS in 289 Mexican ...
