摘要:

针对水动力条件这一泥石流重要的激发因素,提出一套新型的水石分流系统,系统主要由倾斜盖板分流池和虹吸排水管组成.水石分流系统可以高效快速的排泄沟谷内的水体,消除超强水动力条件,对于抑制泥石流发生或减小其规模意义重大.依据水力学相关理论,建立计算分流量和分流率的方法,计算结果与一处实际分流池工程实测数据吻合较好.对影响分流能力的主要参数(盖板长度、宽度和倾斜角度)分别进行了6种不同取值下的分流率计算,结果表明:盖板宽度和角度的变化对于分流影响相当,长度变化所带来的影响最显著,应作为控制分流率时的主要调整对象.

Abstract:

A new type of water-stone shunt system was proposed according to the hydrodynamic condition, which is an important motivating factor of debris flow. The system mainly composed of inclined plate shunt pool and siphon drainage pipe. This system could rapidly discharge the water and eliminated the exceeding hydrodynamic conditions, making great significance to inhibit debris flow occurrence or to reduce its scale. On the basis of hydraulics theory, the calculation method of shunt volume and split ratio was established, which had good agreement with the experimental data measured in an actual shunt pool. The main parameters that affected the separation ability of the structure,including cover plate's length, width and angle,was calculated and analyzed with six different values, respectively. Results show that the change of the plate's length has significant effect on the influence of the separation ability, while that of the plate's width and angle has the same effect.Therefore, the plate's length should be treated as the main adjustment object to control the split ratio.
