Evaluation of safety performance of extremely high slab-faced gravel dams
Yantu gongcheng xuebao, 2017 The structural safety performance of Dashixia concrete face gravel dam (CFGD), an extremely high CFGD in Xinjiang, is studied based on the large-scale triaxial experiments on dam materials and the detailed finite element method-based numerical analyses ...

Plastic strain directions of rockfill materials during loading and creeping
Yantu gongcheng xuebao, 2018 The determination of the incremental plastic strain direction (IPSD) is one of the kernels in elastoplastic constitutive models. It is generally assume that the IPSD depends only on the stress states and is not influenced by the stress increments.

Simulation method for crest cracks in high earth core rockfill dams and its application
Yantu gongcheng xuebao, 2020 The crest cracks are the common dangers during construction and operation of high earth core rockfill (ECRD) dams. The occurrence and propagation of the crack increases the safety risk of the project greatly.

Mathematical model for breach of tailings dam due to overtopping and its application
Yantu gongcheng xuebao, 2017 Based on the non-equilibrium continuous equation and momentum equation for water-sand mixture, considering the impact on the variation of sand volume concentration due to the change of breach slope and bed, a mathematical model is established to describe

A mechanism of failure in shear bands [PDF]
Extreme Mechanics Letters, 2018 We have carried out dilatant plasticity simulations to investigate the process of failure inside a shear band. The constitutive model accounts for possibly inhomogeneous flow within the band, void rotation and void elongation. We found that the material in the band may soften with no increase in the void volume fraction.

Elastoplastic model for cemented coarse-grained materials and its application
Yantu gongcheng xuebao, 2019 Until now, the engineers still doubt about whether the cemented coarse-grained soils can be used in permanent structures such as high rockfill dams. It is mainly due to the fact that the studies on the mechanical properties of the cemented coarse-grained

Yantu gongcheng xuebao, 2021 The leakage of canals in North Xinjiang is serious, and the behavior of expansive canal soil deteriorates rapidly, leading to frequent canal slides. In order to solve this problem, the canals are refilled and rebuilt, and a drainage system is set up at ...

Metabolic Mechanisms in Heart Failure [PDF]
Circulation, 2007 Although neurohumoral antagonism has successfully reduced heart failure morbidity and mortality, the residual disability and death rate remains unacceptably high. Though abnormalities of myocardial metabolism are associated with heart failure, recent data suggest that heart failure may itself promote metabolic changes such as insulin resistance, in ...

Numerical simulation of evolution of viscous debris flows considering interface
Yantu gongcheng xuebao, 2019 Based on the interface theory, taking the corresponding surface of the yielding depth of debris flows as the interface, the viscous debris flow can be divided into ideal fluid and Bingham fluid.
