Abstract The concrete face rockfill dam (CFRD) generally encounters structural health problems during long-term operation. Therefore, it is necessary to study the safety evaluation of CFRDs. This paper proposes a comprehensive method for behavior CFRDs on basis regression relationship and fuzzy recognition model. sub-index established by using method. multiplication scale was adopted determine ...

To study the deformation behavior of high rockfill (HRF) embankment during construction and operation, based on more than a 50-m second-class road reconstruction project from Xunyang to Ankang national 316 in Shaanxi, China, centrifuge model test was performed laws HRF embankment. The results showed following: (i) stable operation; (ii) construction, settlement occurred at top, uplift slope foo...

The determination of shear strength parameters for coarse granular materials such as rockfill and waste rocks is challenging due to their oversized particles the minimum required ratio 10 between specimen width (W) maximum particle size (dmax) tested samples direct tests. To overcome this problem, a common practice prepare test by excluding particles. This method called scalping scaling down te...
