Experimental study of seepage in levee with transverse structure and water barrier

open access: yesGeomatics, Natural Hazards & Risk
A quasi-real-scale experiment was conducted to understand seepage in levees with internal transverse structures. The experiment involved fabricating levees with transverse structures in the same location and using the same method as that in sand levee ...

Evaluation of Actual Creep Length Under Heading up Structures Aprons

open access: yesThe Journal of Engineering Research, 2018
In this paper a 2D finite element model (SEEP2D) is implemented to study the actual head loss along the sheet piles fixed at the ends of an apron of a heading up structure.

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

open access: yesDeep Underground Science and Engineering, EarlyView.
The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in

Design and construction aspects of a geocomposite drainage system in a dam [PDF]

open access: yes, 2012
The drainage system of a dam depends mainly of the available granular material founded near the dam site and it’s quantities. In some cases, the use of natural granular materials can reach an impracticable cost considering the transportation and the ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of
