Embodiment 1
[0037] A method for calculating the critical condition of viscous debris flow blocking the river, comprising the following steps:
[0038] a. Calculate the single-width discharge ratio ε between the tributary ditch and the main river according to formula 1;
[0039]
[0040] Among them, Q 1 Single-width discharge of the main river, unit m 2 / s, Q Z Main river flow, unit m 3 / s, according to the survey, combined with the relevant national norms and design tasks to obtain Q Z , B 1 The average width of the main river at the intersection of the main river and the tributaries, in m, obtained by field measurement B 1 ;Q 2 is the single-width flow rate of the tributary, in m 2 / s, Q n is the debris flow flow rate, unit m 3 / s, according to the survey, combined with the relevant national norms and design tasks to obtain Q n , B 2 The average width of the tributary at the junction of the main river and the tributary,
[0041] The unit is m, and B is obtained by fiel...
