The diversity of the landslide dam structure will result in difference body’s seepage. In this paper, based on two kinds soil bodies different particle gradations, fourteen groups structures are designed to generalize seepage developments and breaking processes. study shows that saturation evolution characteristics dam's have a considerable influence dam’s characteristics. An empirical formula ...

The utilization of the lining type in pressure tunnels is highly dependent on the geological and hydraulic conditions. There are two types of lining, namely concrete and steel lining but steel lining is one of the most expensive arrangements. To decrease the length of steel lining in these tunnels, the concrete lining, which prevents water seepage from the surrounding rock mass, is the appropri...

In seepage problems, the coefficients of permeability in Laplace equation are usually assumed to be constant vs. both space and time; but in reality these coefficients are variable. In this study, the effect of material deformation due to external loads (consolidation) and variation of head in the consolidation process are considered. For the first case, formulation of kx and ky can be defined ...

In the process of piping development, sediment carried by seepage causes change porosity and then permeability coefficient. Therefore, belongs to muddy water (i.e., unstable seepage). Based on theory seepage, new control equation model is established. The generation mechanism development for white fine sand gravel are explored. advantages discussed. results show that not only simpler in form bu...

Seepage is ubiquitous during tunneling in areas with high groundwater tables. The ground settlement trough on a single tunnel well described by Peck’s formula, but it cannot reflect the caused seepage. In this paper, assuming that inside and outside one-dimensional steady-state seepage condition, drainage model of was established. Based principle dynamics, flow calculation formula derived, dewa...

in this paper we investigate the mechanism of internal erosion caused in the right abutment of the shahghasem dam’s spillway. shahghasem dam is an earthen dam located in yasouj, in southwest of iran. a significant hole and pipe have been observed in the corner of the right abutment from upstream view. the foundation is marlstone, which has low cohesion and susceptible for internal erosion and p...

In order to ensure the sustainable growth of rural economy, it is necessary carry out further research on small-scale water conservancy projects and solve seepage issue in areas. Based application significance analysis anti-seepage technologies, along with specific examples, this paper specifically discusses high-pressure jet technology, so as provide reference for development engineering const...

Seepage is one of the important factors involved in natural flow conditions, contributing to changes turbulence patterns and morphological due transport sediments. This sediment particles influences development fluvial bedforms any river channel. However, previous research on dynamics has not considered influence seepage field over bedforms. The present experimental aims explore behavioral turb...

*Correspondence: [email protected] Department of Applied Mechanics, Chalmers University of Technology, Hörsalsvägen 7, 412 96 Göteborg, Sweden Abstract Background: Seepage in porous media is modeled as a Stokes flow in an open pore system contained in a rigid, impermeable and spatially periodic matrix. By homogenization, the problem is turned into a two-scale problem consisting of a Da...
