Numerical modeling of earthen dam breach due to piping failure被引量:8
《Water Science and Engineering》2019年第3期169-178,共10页Sheng-shui Chen Qi-ming Zhong Guang-ze Shen 
supported by the National Key Research and Development Program of China(Grant No.2017YFC0404805);the National Natural Science Foundation of China(Grants No.51779153 and 51539006);the Central Public-interest Scientific Institution Basal Research Fund(Grant No.Y717012);the Natural Science Foundation of Jiangsu Province(Grant No.BK20161121)
Based on model tests of earthen dam breach due to piping failure, a numerical model was developed.A key difference from previous research is the assumption that the cross-section of the pipe channel is an arch, with a...
