Knowledge Extraction via Machine Learning Guides a Topology‐Based Permeability Prediction Model

open access: yesWater Resources Research, Volume 60, Issue 7, July 2024.
Abstract The complexity and heterogeneity of pore structure present significant challenges in accurate permeability estimation. Commonly used empirical formulas neglect its microscopic and topological characteristics, thus lacking accuracy and adaptability. While machine learning (ML) and deep learning (DL) models demonstrate promising performance, but

Clogging and Unclogging of Fine Particles in Porous Media: Micromechanical Insights From an Analog Pore System

open access: yesWater Resources Research, Volume 60, Issue 1, January 2024.
Abstract Pore clogging and unclogging in porous media are ubiquitous in subsurface hydrologic processes, which have been studied extensively at various scales ranging from a single pore to porous‐medium samples. However, it remains unclear how fluid flow, particle rearrangement, and the arching effect typical of cone‐shaped pore geometry interact and ...

Time‐Dependent Fuzzy Reliability Analysis of Concrete Slab during the Initial Water Storage Period of CFRD: A Case Study

open access: yesAdvances in Civil Engineering, Volume 2024, Issue 1, 2024.
The concrete‐faced rockfill dam (CFRD) has been widely constructed worldwide, and the reliability of the concrete panels, the most important containment structure, is critical to the safety of the CFRDs and downstream communities. Several practical projects show that concrete slab cracking usually occurs during the water storage period, which can be ...

Development and Application of a Percolation Velocity Monitoring Method in Multiphase Percolation Physical Experiments

open access: yesGeofluids, Volume 2024, Issue 1, 2024.
Unlike conventional single‐phase seepage monitoring methods, monitoring multiphase flow in porous media is more complex. This paper addresses this complexity by analyzing the heat transfer in porous media models under multiphase seepage conditions.

A New Method for the Compaction Quality Inspection of High Rockfill Dams Based on 3D Laser Scanning Technology

open access: yesStructural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
The compaction quality is directly related to the deformation and stability of the rockfill dam. Measuring the test pit volume efficiently and accurately is the most critical step during the compaction quality inspection. A new method for calculating the test pit volume based on point cloud data is proposed.

Interconnection between Stress-strain State and Pore Water Pressure in Earth Core Rockfill Dam

open access: yesRussian Journal of Building Construction and Architecture
Statement of the problem. Analytical methods of analysis do not allow explaining the effect of fast dissipation of pore water pressure in clay cores of rockfill dams, which is observed during construction period. Research of this effect is accomplished by joint solving of the stress-strain state task and the problem of the seepage regime of a high dam ...
