It is commonly accepted that the macroresponse of soil depends significantly on microscopic particle characteristic features, such as size, shape, and roughness. These parameters can be obtained readily by dynamic image analysis each individual particle, enabling quantification morphologies. This study investigated variation calcareous sand morphology before after one-dimensional normal compression. The tests employed a large oedometer cell (231.6-mm inner diameter 155-mm height) coarse...
This paper investigated the differences for hydraulic characteristics in a single fracture between using Navier–Stokes (N–S) equation and Darcy's law, which would be benefit to understand seepage mechanism fracture. A numerical model of radial flow was established considering aperture size water injection rate. Some conclusion could given. First, law only described when rate small pressure response have linear relationship. While N–S describe nonlinear characteristics, resulting better...
The reduction of carbon emissions from land use (CELU) is critical for China to achieve neutrality, which may be greatly facilitated by trading policies. Previous studies the emission effects policies focused mostly on source emissions, and there a lack research comprehensive perspective sources sinks. Understanding effect CELU help improve evaluation system policies, as well provide important implications construction China’s market in context global neutrality. Here, based current...
Since the surrounding rocks of underground tunnels are frequently suffered from dynamic disturbance mechanical percussion drilling and explosive blasting, it is significantly meaningful to investigate properties failure behaviors rock material with a tunnel-shaped opening under loads. In this work, seven groups prismatic samples, including intact samples circular three kinds diameters, square opening, horseshoe-shaped D-shaped were prepared for compressive loading. The results show that...
In general, exploitation of rock materials, such as limestone or granite exploitation, can cause serious damage to the environment near a mine area. With economic development and ever-increasing demand for ore resources, mining activities have induced very environmental issues in China. Therefore, restoration work around mines China is urgently required. This study explores Chuankou open-pit quarry Tongchuan City, Shaanxi Province, Northwest China, engineering case. The caused by over 40...
In this paper, the effect evaluation and production prediction of staged fracturing for horizontal wells in tight reservoirs are studied. Firstly, basic characteristics value introduced, their geological characteristics, flow mechanism permeability model analyzed application grey theory analysis is discussed. Considering problems reservoirs, a BP neural network based on deep learning proposed. Due to interference multiple physical parameters complex functional relationship development...
Soil particle size distribution is a critical parameter in geotechnical and hydraulic engineering, particularly applications such as dam seepage monitoring, building foundation assessments, sediment transport. This study presents novel algorithm for estimating soil sizes by analyzing their falling velocities water, combining optical flow computation with chaotic motion analysis. To address the limitations of classical Horn Schunck method, its sensitivity to large displacements brightness...
Fissured expansive soils exhibit pronounced moisture-induced swelling, posing significant risks to the stability of geotechnical structures such as dam foundations and core zones. To improve predictive capacity in environments, this study developed a back-propagation (BP) neural network model estimate swelling behavior fissured soils. The incorporated four key parameters—fissure ratio, dry density, initial moisture content, overburden pressure—and was implemented MATLAB using three-layer...
Coal-mining subsidence causes ground fissures and destroys surface structures, which may lead to severe casualties economic losses. Time series interferometric synthetic aperture radar (TS-InSAR) plays an important role in deformation detection monitoring without the restriction of weather sunlight conditions. In addition, probability integral method (PIM) is a movement model that widely used field mining subsidence. recent years, integration TS-InSAR PIM has been extensively studied. this...
