Hydraulic and Hydroclimatic impact on dam seepage of civil and structural mechanisms with application of deep learning models

Results in Engineering
Seepage is a critical problem in earthfill dams which threatens the dam's stability and safety owing to extreme shifts in climate change with the rise in water intake in dams.

Large-scale shear box tests to determine rockfill parameters

, 2016
A 160 (525 ft) m high asphalt concrete core rockfill dam is developed in an area of very high seismicity in Cetin, Turkey. Topographical constraints of the dam footprint impose a steep outer geometry of the dam, requiring the geotechnical properties of ...

Non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation

, 2014
This study investigates the non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation for various concrete slab thicknesses from 30 to 100 cm thick. The effect of the friction in the concrete slab rockfill interface on

Nonlinear Static Analysis of an Asphalt Concrete Core Dam dor Comparison of Three Constitutive Models

Archives of Civil Engineering, 2012
The goal of this work is to compare different constitutive models in the nonlinear static characteristic analysis of asphalt concrete core dams. The Duncan E- μ model, Duncan E-B model and double-yield-surface model are three major constitutive models in

Pore pressure in the core of ultra-high earth core rockfill dam at consideration of stress-strain state

Magazine of Civil Engineering
In the clayey core of the rockfill dam, pore pressure always appears, which may present a serious threat to the dam safety. Therefore, in the middle of the 20th century, there started the development a theory of clayey soil consolidation in cores of ...
