The parameters of the constitutive models used in design rockfill dams are associated with a high degree uncertainty. This occurs because comprised numerous zones, each different soil materials, and it is not feasible to extract materials from such structures accurately ascertain their behavior or respective parameters. general approach involves laboratory tests using small material samples emp...

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...

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 ...
