摘要
通过1∶50局部定床正态模型,对二期明渠截流龙口水力特性、戗堤的抛投进占、截流对通航的影响进行了试验。试验表明二期截流工程具有龙口流速大、落差较大、水深较浅的特点;采取护底加糙同时上游角按45°抛投进占方法可有效地减少抛投强度和大块石的用量。
Hydraulic characteristics,throwing materials and influence of the diversion closure on navigetion is studied by the undistorded model with the scale of 1∶50.It is shown that the diversion closure project has the characteristics of large velocity,lager water drop and shallow water depth.The intension of dumping and the dosage of big stones can be decreased by apron,giving roughness and dumping materilas at the 45°.
