In this paper, the method combined the “ s ” shape sediment control dam with the dredged channel has been put forward 為此,在比較各種疏浚方案效果的情況下,提出了挖泥槽與增設折線型防淤堤相結(jié)合的清淤疏浚措施。
In order to reduce the re-deposit volume of the dredged channel, the method must be based on decreasing the oncoming sediment, changing the mouth site, builting the sediment control dam and raising the reservoir level 為了最大限度地減小疏浚挖槽的回淤量,必須依靠控制上游來沙量、調(diào)整入水口門位置、加設防淤堤及提高庫水位等手段,而不能通過調(diào)整挖泥槽寬度、位置及數(shù)量等措施來達到目的。
