摘要
涝河发源于秦岭北麓,系渭河支流。70年代初,对其中、下游河段曾进行过渠化治理,但每逢洪水,坍塌毁损工程仍有发生。通过模型试验又作了如下改建治理:运用梯级溢流坝调整控制河床平衡比降,坝下游设消力池,合理确定河床宽度,使河道流态改善,流速分布均匀,制止了水毁工程的发展。
The Lao River,a tributary of the Wei River.rises in the northern foot of Qinling mountain.The middle and lower reaches of the river have been channelized in the early 1970's,but the events of cave-in and damage still happen wherever there is a flood.Therefore,the following aspacts have been corrected and im- proved through model tests:readjust and control the bed slope,add a stilling basin at the downstream of the dam,and rationally determine the width of the channel.As a result,the flow pattern of the channel has been improved,velocity evenly distributed and the development of damages checked.
