Leakage is a major safety issue that, if left unchecked, may result in dam failure by various mechanisms. There is enormous pressure on dam operators to repair leaks without significant delays. Frequently, the need to reduce the risk of failure or control water loss has led to costly remedial repairs that are planned and executed without a complete understanding of the problem. A lack of approp...

Polymer anti-seepage walls have been widely used in the reinforcement projects of earth dams. Dam crest is always supposed to meet requirements traffic load which has significant influence on dam body and wall. In order analyze coordination characteristics deformation between polymer wall under loads, a 3D finite element model an that considers coupling effect seepage field stress was establish...

In recent years a number of embankments were designedwith concrete overtopping protection shaped in a stepped fashion. During large overflows on stepped chutes, there is no skin friction between mainstream and steps, and flow resistance is basically form drag. Alterations of flow recirculation and of fluid exchanges between free-stream and cavity flow are discussed in this study. A comprehensiv...

Dam safety is an important issue as it directly influences environmental and life losses. Embankment material embankment core are factors that contribute to determining the size hydraulic characteristics of breach occurs due dam failure. The current topic present analysis impact materials properties on dimensions overtopping failure using 2D-HEC-RAS software with aid RAS-Mapper. was made by Dig...

During the spring of 2003, the downstream slope of an embankment dam began to move during an extreme flooding event. The current study was implemented to evaluate the slope stability of the embankment and as a case-study to compare the limit equilibrium and continuum modeling methods. Initially, stability analyses were performed using conservative shear strength of soils estimated from both bor...

The stability of tailing dam has an important influence on the surrounding ecological environment and the security and property of people. This article, from the micro perspective, analyzes of the water-tailing chemical interactions and process and analyzes its effects on tailing micro structure and dam stability. The experimental results show that ferrous iron in water(PH=9.5-10.3) is constant...

High-resolution seismic reflection has been used successfully to characterize material and investigate a variety of problems associated with earthen dams and abutments. Limitations and challenges of seismic reflection when interrogating these structures and lithologies are nontrivial and require very critical thinking. Seismic reflection has proved an effective tool for mapping confining units ...

Abstract This article analyzes the application of logistic regression with use ICA to detect leakages and in flood embankments. As a result study, model analysis was carried out where electrical impedance tomography tests were performed for one two rows electrodes. For results obtained, it possible verify evaluation usefulness algorithms reconstruction images derived from tomography. The propos...
