Shaking table tests of subway station-bridge complex structure to evaluate nonlinear seismic response under strong earthquakes

To investigate the nonlinear seismic performance of subway station-bridge complex structures during strong earthquakes, shake table tests were conducted on specimens consisting of a two-story three span subway station and a three-span variable cross-section steel box girder bridg...

Initiation mechanism of irrigation-induced retrogressive loess landslides on the South Jingyang Tableland, China

Abstract Repeated sliding disturbs the slope structure and degrades soil mechanical properties, promoting the progressive development of retrogressive loess landslides on the South Jingyang Plateau, China. These landslides progressively encroach upon the plateau surface and have...

A Frequency-Domain Blind Deconvolution Method Based on Weight Feature Extraction and Its Application in Rolling Bearing Fault Diagnosis

Rolling bearing faults typically exhibit sideband structures in the frequency domain, yet conventional blind deconvolution methods operate in the time domain and rely on prior fault periods. To reduce this dependence and broaden applicability, this paper presents a frequency-doma...

CO2 Gas Channel Identification in the CCUS-EOR Process Based on the Fuzzy Comprehensive Evaluation Method

In CO2 flooding, variations in mobility and formation heterogeneity may cause gas to traverse high-permeability or interconnected channels, leading to ineffective gas circulation. This limits recovery rates, ultimately leading to reduced financial benefits. Consequently, the iden...

Gas–Solid Two-Phase Flow-Induced Pipeline Wear in CAES: Enhancing Long-Term Durability for Energy Conversion and Storage Integration

In salt cavern compressed air energy storage (CAES) systems, slag particles entrained by high-pressure airflow can cause pipeline wear and flow instability, posing challenges to long-term operational safety. However, direct experimental studies are constrained by high-pressure, l...
