Zhongguo dizhi zaihai yu fangzhi xuebao, 2022 After the Wenchuan earthquake, many loose solid sources accumulated in the channel, which increased the probability of debris flow. It was difficult to calculate the dynamic reserves of debris flow sediment source accurately. Based on field investigation,

Influence of coarse-grained content in the gravelly soil on steady seepage of high earth-rock dam
Shuili Shuiyun Gongcheng Xuebao, 2021 Gravelly soil has been mostly used as the core material of the high earth-rock dam. When the coarse-grained content of a gravelly soil (referring to the mass fraction, the same below) may exceed 50%, the coefficient of permeability of a gravelly soil is ...
