Application of fractal theory in rockfill rheology
Shuili Shuiyun Gongcheng Xuebao, 2017 The rockfill material crushes during the process of rheology and the fractal dimension of rockfill material varies with time. Based on the basic rule of rheological process of coarse-grained soils, the fractal theory is applied into the analysis of ...

Numerical model for breach of concrete face sand-gravel dams due to overtopping
Yantu gongcheng xuebao, 2019 Based upon the data of field investigations and back analysis of centrifugal model tests for the beach case of the Gouhou concrete face sand-gravel dam (CFSGD), a numerical model for breach of CFSGD is developed. The major highlights of the model are the

Numerical analysis of optimization of revetment structures of soil bank slopes of inland rivers
Yantu gongcheng xuebao, 2020 The revetment structure can reduce the damage of soil bank slopes caused by water erosion, but its influences on the physical and mechanical processes such as seepage and deformation of the existing bank slopes should be fully considered in practice ...

Numerical modeling of breach process of landslide dams due to overtopping and its application
Yantu gongcheng xuebao, 2018 As a production of natural process, the landslide dam has poor structural stability, and most of which will finally fail due to overtopping, which will pose tremendous risks to the people and property in the inundated area.
