In order to safely and efficiently use soft rock aggregate cemented dams in red bed regions promote the development of widely sourced sand gravel dam materials, Jinjigou project China applied for first time construction material dams. This article further explores concept from conducting on-site direct shear tests research on ratios invents a new structure method by combining with rockfill. als...

Settlement prediction is of great importance for safety control concrete-face rockfill dams (CFRDs) during the operation stage. However, accuracy achieved by commonly used hydrostatic–seasonal–time (HST) methods, without consideration previous conditions influencing factors, not competitive. Moreover, in most settlement data at each monitoring point are modeled individually; correlation relatio...

Dam failures are examples of man-made disasters that have stimulated investigation into the processes related to failure different dam types. Embankment breaching during an overtopping event is one major modes for this type, comprising both earthfill and rockfill dams. This paper presents results a series laboratory tests on breach initiation progression in Especially eight 1 m-high 1:10 scale ...

The particular interest produced by the seismological characteristics impacting structural response has given a new challenge in performance-based design of high dams. Recent research shown that frequency and amplitude inherent ground motion (GM) records govern dynamic Therefore, these have been accepted incorporated into seismic codes dams most countries. However, duration strong GMs, as one c...

To address the uncertainty problem in assessment of overall safety trend dams and selection warning indicators, an Extended Cloud Model (ECM) combined with Analytic Hierarchy Process (EAHP) method is proposed this study. In new approach, different factors reflecting dam monitoring have been considered as a fuzzy system. Considering characteristics forward cloud model backward model, original da...

Inversion analysis is usually an efficient solution to process the monitoring data of earth-rockfill dams. However, it still difficult obtain calculation results that are consistent with due different construction statuses. To deal this situation and introduce a new improve accuracy, general method inversion based on back-propagation neural networks original step-by-step assuming parameters con...
