Keywords: Rockfill creep Particle mechanics method Water weakening Wetting–drying cycles Particle breakage Abrasion a b s t r a c t Rockfill is an important construction material for infrastructure engineering, such as dams, railways and airport foundations, which display a long-term post-construction settlement. However, the main mechanisms for rockfill creep and weathering influence still rem...

According to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. Hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. In various constructed physical models of porous media, the effect of several variables such as ...

The Triassic Yanchang Formation in the Ordos Basin is one of main exploration targets. Based on detailed outcrop at southern margin Basin, combined with previous results, a systematic analysis lithology, rock assemblage, sedimentary facies characteristics and temporal evolution carried out. results show that Changchang 9 oil-bearing group can be divided into lithofacies types, three types facie...

Abstract The consolidation of earth and rock dam foundations its effect on stability is a key concern in water conservancy transportation projects. It common to use the vacuum combined pre-pressure method deal with soft ground foundation, where reasonable selection soil coefficient one important factors determine success project. In this paper, numerical simulation used study strength law found...

differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. a numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. reservoir is modeled using the eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. dynamic equilibr...
