Evaluation of the Impact of Incident Wavefield Modeling on Soil‐Structure Interaction of Buildings Using Broadband Physics‐Based 3D Earthquake Simulations

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite the complexity of real earthquake motions, the incident wavefield excitation for soil‐structure interaction (SSI) analysis is conventionally derived from one‐dimensional site response analysis (1D SRA), resulting in idealized, decoupled vertically incident shear and compressional waves for the horizontal and vertical components of the ...

Fault Recognition Method and Application Based on Generative Adversarial Network

Energy Science &Engineering, EarlyView.
ABSTRACT In view of the limitation of generalization ability faced by deep learning in fault identification, especially in the case of complex underground geological conditions and variable seismic data characteristics, it is often ineffective to directly use the network based on synthetic data training for fault prediction of real data.

Hydrocarbon Potential of the Pabdeh Formation: Geochemical Insights Into Immature Source Rock Capabilities

Energy Science &Engineering, EarlyView.
ABSTRACT The Pabdeh Formation (Paleocene‐Oligocene) is one of the hydrocarbon‐generating formations in the Zagros sedimentary basin. In this study, to evaluate its hydrocarbon potential and the distribution of organic matter maturity, samples were collected from oil fields in southwestern Iran and the Dezful embayment and analyzed geochemically.

Characterization of Pressure Pulsation Propagation in a Pump‐Turbine Based on the Same‐Frequency Tracking Method

Energy Science &Engineering, EarlyView.
ABSTRACT Pressure pulsation is a key factor affecting the safe and stable operation of pump‐turbines. This article is based on same frequency‐tracking method on the pressure pulsation propagation characteristics of pump‐turbine during generation mode. The numerical simulation is validated by experimental study on a model pump‐turbine.

Experimental Study on Prevention of Coal and Gas Outburst by Hydraulic Fracturing in High Gas Coal Mine in Yangquan Mining Area

Energy Science &Engineering, EarlyView.
ABSTRACT To investigate the hydraulic fracturing mechanism of high‐fluid wells in the Yangquan mining area, coal seams from the Xinyuan and Xinjing mines were selected as research subjects. Experiments were conducted using the TCQT‐III low‐permeability coalbed gas‐phase displacement and production enhancement apparatus, along with the FINESORB‐3120 ...
