Applied Sciences, Vol. 16, Pages 8874: Research on Optimization of Material Transportation Scheduling for Water Conservancy Engineering Considering Emergency Response to Vehicle Malfunctions

6+ day, 3+ hour ago   (453+ words) In-transit vehicle malfunctions during material transportation in water conservancy construction can cause delivery delays, disrupt subsequent tasks, and lead to duplicate material requisitions. To address these issues, this study develops a material transportation scheduling optimization model that explicitly incorporates vehicle-malfunction…...

Applied Sciences, Vol. 16, Pages 8363: Mechanism of Fracture Network Propagation and Permeability Evolution in Naturally Fractured Rock Under Pulse Fracturing

3+ week, 1+ day ago   (473+ words) Natural fractures dominate fracturing effects and well production. Conventional fracturing fails to fully activate multi-scale fractures, and most simulations adopt homogeneous rock assumptions, lacking systematic analysis on fracture propagation and seepage evolution in heterogeneous fractured formations, while the natural fracture…...

Applied Sciences, Vol. 16, Pages 8812: Optimised Machine Learning for MASW-Based Zonation of Weak Alluvial Soils Using Anchor-Based SPT/SCPT Calibration

1+ week, 2+ day ago   (433+ words) Weak alluvial soils are difficult to delineate where penetration-test data are sparse and stiffness varies rapidly with depth. This study presents a novel goal-attainment-optimised machine learning framework that combines multichannel analysis of surface waves (MASW) with anchor-based standard penetration test…...

Applied Sciences, Vol. 16, Pages 7950: Numerical Analysis of Hydraulic Fracture Propagation Behaviors in Ultra-Deep Lattice-like Fractured Reservoirs

1+ mon, 3+ day ago   (447+ words) Ultra-deep lattice-like fractured carbonate reservoirs, formed by multi-period tectonic movements, feature strong heterogeneity, multi-scale fracture nesting, and anisotropic in situ stress. However, hydraulic fracture (HF) propagation behaviors within these complex formations remain poorly understood. In this study, using an unstructured…...

Applied Sciences, Vol. 16, Pages 8131: Zonal Evolution and Fractal Characterization of Coal Fracture Networks Around Gas Drainage Boreholes

4+ week, 1+ day ago   (569+ words) To elucidate the structural evolution of fracture networks around gas drainage boreholes and their controlling mechanisms on grouting sealing performance, a coal seam in the Zhongmacun Mine (No. 2-1 coal seam) was selected as the engineering background. An integrated approach combining…...

3+ week, 1+ day ago   (501+ words) Rock cohesion (c) and angle of internal friction (φ) are core parameters for rock mass stability analysis and engineering design; however, traditional triaxial tests are costly and time-consuming, limiting their availability in preliminary engineering assessments. To address this limitation, this study…...
