摘要
从防灾减灾的角度,探讨了尾矿型泥石流的冲击高度对尾矿库区下游人员和建构筑物的重大影响,应用正交试验的方法,以尾矿库坝高、库容,下游沟谷的坡降和弯曲系数为影响因素,研究了不同影响因素对冲击高度的影响规律及作用程度,并对试验结果进行回归分析,得到了泥石流冲击高度的预测数学模型。
The influence of impact hight of tailings debris flow on the people evacuation and build- ing site selection is analyzed in detail form the perspective of disaster prevention and mitigation. Regarding the high and capaetity of tailings dam, downstream valley slope and bending coefficient as influence fac- tors, some relative research work on the infulence law and extent of different influence factors is done by adopting the orthogonal experiment method. In addition, the experimental data is regression analyzed so as to obtain the forecast mathematical model of the height of debris flow impact.
