Relationship Between Minimum Creep Length and Maximum Exit Hydraulic Gradient in Sheet Pile Cofferdams

Geotechnical and Geological Engineering, 2022
Sheet pile cofferdams are temporary structures used widely to support the excavation pits in sandy soils. Double-walled and circular cofferdams are two of the commonly seen cofferdam shapes. One of the main concerns pertaining to these sheet pile cofferdams is the excavation base stability against piping failure. Factor of safety against piping failure

Analytical Determination of Seeping Soil Slopes of a Constant Exit Gradient [PDF]

ZAMM Zeitschrift Fur Angewandte Mathematik Und Mechanik, 2002
Soil slopes satisfying the condition of a constant exit gradient and the seepage face condition are studied by the methods of complex analysis. For a given slope \(y=F(x)\) the exit gradient \(|\nabla h|_F \) is determined from the flow problem. In this paper the authors consider the case when \(|\nabla h|_F =J/k\) along the slope, where \(J\) is a ...

Gradient Deconfliction-Based Training For Multi-Exit Architectures

2020 IEEE International Conference on Image Processing (ICIP), 2020
Muiti-exit architectures, in which a sequence of intermediate classifiers are introduced at different depths of the feature layers, perform adaptive computation by early exiting “easy” samples to speed up the inference. In this paper, we propose a new gradient deconfliction-based training technique for multi-exit architectures.

Quantifying groundwater dependency of riparian surface hydrologic features using the exit gradient

Hydrological Processes, 2016
AbstractNumerical groundwater flow models necessarily are limited to subsurface flow evaluation. It is of interest, however, to examine the possibility that, for unconfined aquifer systems, they could be used to proportionately measure the magnitude of seepage they estimate when these aquifers intersect the landscape surface. Our goal in this study was

Effect of Drain Pipes on Uplift Force and Exit Hydraulic Gradient and the Design of Gravity Dams Using the Finite Element Method

Geotechnical and Geological Engineering, 2021
The effects of diameter and location of drain pipes on the uplift force and exit hydraulic gradient for a gravity dam are investigated. A numerical model of a gravity dam is simulated using the finite element method. The results indicate that drain pipes under a gravity dam reduce the uplift force and exit hydraulic gradient.

Investigation of the effect of the different configurations of double-cutoff walls beneath hydraulic structures on uplift forces and exit hydraulic gradients

Journal of Hydrology, 2020
Abstract In the design of hydraulic structures, cutoff walls are needed to reduce uplift force (U) and the exit hydraulic gradient (GR). Usually two cutoff walls are required; an upstream cutoff wall is used to reduce the resultant of uplift force and a downstream cutoff wall is used to reduce the exit hydraulic gradient.
