本文在直線渠道起始坡度1%之動床試驗中利用「成功筐網(C.K.P.B)」導流工法來探討底床的變化。本文中所進行的試驗主要是將筐網擺設在渠道的左邊,藉由改變筐網的參數(間距、角度、支數)變化,研究不同參數對底床影響的特性。試驗中發現,改變間距或是改變支數,使得筐網對於後方的保護長度延長,對於底床變化的程度,比改變角度還要來得顯著。可以明顯觀察到在筐網架設的後面,左岸呈現出淤積;右岸呈現出沖刷的現象。由此結果顯示,「成功筐網(C.K.P.B)」導流工法可利用在天然河道的底床或是堤岸的保護上。
The main purpose of this paper is about observing the variation of bed by using Cheng-Kung Porous Basket(C.K.P.B) in a straight channel experiment. The experiments of this paper are mainly setting C.K.P.B at the left bank of a straight channel, discuss the differences of each setting by changing the parameters( spacing、angle、count ) of C.K.P.B. By the results of these experiments, changing spacings or counts would extend the protective length, which is more obviously than changing angles. It’s clear to find that behind the C.K.P.B, the left bank has deposition, and the right bank has scouring. The appearance of these experiments shows :C.K.P.B could be apply in natural river channel bed or the protection of embankment.
