Experimental study on slope sliding and debris flow evolution with and without barrier

摘要: Abstract A constitutive model on the evolution of debris flow with and without a barrier was established based theory Bingham model. certain area Laoshan Mountain in Nanjing, Jiangsu Province, China chosen for experimental study, slope sliding detection system utilized. The change curve soil moisture content attained, demonstrating that shallow layer increases faster than deep layer, growth rate steep is large under first weak rainfall, gentle significantly affected by second heavy rainfall. For slope, occurs upper surface rainfall further develops along top platform lower surface, while at part because high runoff velocity, meaning failure occurring there more serious. When placed position separated distributed early had less ability to carry solids, variation greatest depth erosion pits slopes not significant.
