Interconnection of karst systems and flow piracy through karst collapse in layered carbonate rocks

Environmental Earth Sciences, 2009
A new mode of interconnecting karst systems separated by impermeable bed due to karst collapse was discovered in the study of dam site in Guizhou, South China. Karst flow may be diverted from conduits in one layer to another, thus forming a connected karst system.

Mechanical behavior of groundwater seepage in karst collapse pillars

Engineering Geology, 2013
Abstract Groundwater inrush has an impartible relationship with geological structures such as karst collapse pillars (KCPs), which are widely distributed in North China. In order to study the mechanism of groundwater inrush from coal seam floor, the variable mass dynamics and nonlinear dynamics were introduced.

Mechanism of Shallow Soil Cave–Type Karst Collapse Induced by Water Inrush in Underground Engineering Construction

, 2020
Water inrush disasters are the main cause of karst collapse. In this study, a physical model test was conducted to investigate the mechanism of karst collapse.

Regional risk assessment of karst collapse in Tangshan, China

Environmental Geology, 2001
This paper discusses the reasons why the number of karst collapses has been increasing in Tangshan, China, since 1978. It gives the main factors that influence the regional risk of karst collapse and the method for assessing it. Using the risk assessment method developed, three zones in downtown Tangshan, with different risk levels, were delineated ...

Prikaz knjige "Atlas of Karst Collapses"

Hrvatske Vode, 2022
Radi se o jednoj od do sada sedam objavljenih knjiga iz nove serije „Advances in karst science (Napredci u znanosti o kršu)“ jednog od najvećih svjetskih izdavačkih kuća Springer. Knjiga je osobito aktualna za hrvatske stručnjake i za Hrvatsku u kojoj su se kolapsi, tj. urušavanja u kršu značajno intenzivirali kao posljedica nedavnih potresa.

Risk evaluation of Karst collapse using GIS and RS

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
This article extracts and analyzes disaster information by using GIS and RS technology. It determines the weights by using the Analytic Hierarchy Process (AHP), and it constructs risk evaluation model to do risk evaluation of geological disasters. In this paper, Lai bin, Jili of Guangxi Province is selected as an example to evaluate the risk of Karst ...

Karst collapse in cities and mining areas, China

Environmental Geology and Water Sciences, 1988
Karst collapse is a dynamic geological phenomenon, in which the rock mass or deposits overlying the karstified zone subsides down along the karst cavity, resulting in a collapse pit or sinkhole. After discussing the typical examples of collapse emerging in the karst cities and mines in provinces and regions of South China, such as Guangdong.

Stability Charts for the Collapse of Residual Soil in Karst

Journal of Geotechnical and Geoenvironmental Engineering, 2009
Collapse of the residual soil over bedrock cavities often occurs during construction in karst terrain, particularly when the thickness of the residuum is reduced during excavation. Even if an estimate of the strength of the residual soil is known, uncertainty with respect to the size/geometry of the subterranean voids makes a detailed analysis ...

Urban development in karst and collapse-prone geologic environments

Carbonates and Evaporites, 2013
The development of marginal land necessitated by urban sprawl is producing undesirable consequences derived from inadequate design or construction, or both, of storm water systems in karst and collapse-prone geologic environments. The St. Peters, Missouri karst area is presented as an example. Sufficient knowledge of the geohydrologic setting, combined
