Summary editorial for karst hydrogeology: advances in karst collapse studies
Environmental Earth Sciences, 2018Karst collapses occur in various sizes and by various mechanisms. No karst collapses are the same, and each needs to be treated individually. Decades of investigation of and experience with these collapses make it clear that addressing karst collapse hazards requires a multi-disciplinary approach that integrates geomorphology, engineering geology ...

Multi-source image feature extraction and segmentation techniques for karst collapse monitoring
Frontiers in Earth ScienceKarst collapse monitoring is a complex task due to data sparsity, underground dynamics, and the demand for real-time risk assessment. Traditional approaches often fall short in delivering timely and accurate evaluations of collapse risks.To address these

Seepage property of karst collapse pillar: experiments and engineering applications
Arabian Journal of Geosciences, 2021The Karst collapse pillar (KCP) is a special geological structure, which is easy to form the fissure channels between the coal seam working face and the aquifer to cause the water inrush disasters. The KCP was sampled on site in this paper. The confined uniaxial compression test was carried out on the KCP to simulate its field consolidation, and ...

Study on Field and Numerical Analysis of Karst collapse as Railway Hazard
Geotechnical EngineeringThe vulnerability of karst ecosystems and the weak mechanical performance of caves pose hidden risks in railways, leading to increased karst collapses. To analyze karst collapse as a railway hazard, we selected the Beijing-Guangzhou Railway, China line ...

New advances in karst collapse research in China
Environmental Geology, 2002Until 2000, more than 1,446 karst collapse events and 45,037 sinkhole pits have been documented in China. In this paper, focusing on new achievements of karst collapse research in China, a large-scale model experiment, a method of risk assessment and data management of karst collapse based on geographic information system technology are introduced for ...

Karst Collapse Mechanism and Criterion for Its Stability
Acta Geologica Sinica - English Edition, 2001AbstractKarst collapse, caused by natural or artificial abstraction of groundwater, has been a focus of environmental geological problems for its ever‐increasing hazardousness. The potential erosion theory and vacuum suction erosion theory, which reveal the origin of karst collapse macroscopically, are popularly accepted.
