Salt accumulation and its controlling factors in saline soil profile of Yellow River Delta

Guan'gai paishui xuebao
【Objective】Soil salinization is a major threat to agricultural productivity in the Yellow River Delta, where shallow groundwater and high soil salinity often result in salt accumulation in the root zone.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

2D Groundwater Depth for Analysis of The Zone Unconfined Aquifer

INSIST, 2017
Abstract—Changes in land use have occurred quite significant in the city of Pekanbaru. The increasing of building spaces, the decreasing of plantations and forests are continues to grow with the increasing of population and industries. This means, it can cause impact on   groundwater resources.

Explainable hybrid stacking ensemble method for hard rock pillar stability prediction and engineering applications

Deep Underground Science and Engineering, EarlyView.
This research proposes an interpretable hybrid stacking ensemble framework, optimized by the Sparrow Search Algorithm, to enhance hard rock pillar stability prediction. By integrating six machine learning models—k‐nearest neighbors, support vector machines, random forests, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, and Light Gradient ...

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.
