基于最大落差的立堵截流风险率模型及计算

End-dump river closure risk probabiliiy model and its calculation based on maximum drop

用立堵截流的最大落差确定抛投材料最大粒径的方法 ,建立了相应的风险率模型 ,给出了分流建筑物内的水流流态为有压淹没流时的风险率计算方法 ,并进而讨论了风险率的几个重要特性 .

By means of the maximum drop to determine the maximum diameter of the dumped material, the corresponding risk probability model is established. A calculation method of risk probability is also introduced when the state of flow in the diversion structure is submerged discharge of pipe flow. Some important features of risk probability are discussed.
