丁坝丁坝spur diked ingba丁坝(s pur dike)与河岸正交或斜交伸入河道中的河道整治建筑物。丁坝有长短之分，长者使水流动力轴线发生偏转，趋向对岸，起挑馏作用;短者起局部调整水流保护河岸的作用。由丁坝组成的护岸工程，能控导溜势，保护堤岸，又有束狭河床、堵塞岔口和淤填滩岸的作用。丁坝由坝基和坝头组成，其平面形状呈直线型或拐头型。坝头多为流线型、圆头型或斜线型(图1)。坝头 流线型圆头型斜线型 图1丁坝外形示意图丁坝可分潜水坝或非潜水坝，在设计时，潜水坝顶可以过水，非潜水坝顶不能过水。坝轴线和水流方向垂直的称正交丁坝(图2);坝轴线与水流夹角大于90。者称上挑丁坝，小于90’者称下挑丁坝(图3、图4)。坝身透水的称透水丁坝，不透水的称不透水丁坝。不卜、 飞饭~~~一一代正交丁坝示意图飞溜向烂。一。~~~~丈，一一一一\扁图3上挑丁坝示意图/ //// /万 /\丈资尹众坝出图4下挑丁坝示意图透水丁坝控制水流作用较强，由石料、土料、混凝土预制构件或沉排铺砌构成。透水丁坝可将一部分水流挑离河岸，起控导水流作用，另一部分水流透过丁坝流向坝田，减缓流速，使泥沙沉积，缓流落淤效果较好。透水丁坝可用桩柳、桩及妈楼等构筑，亦可用混凝土桩，设计丁坝时，要根据流势与治导线的要求，确定轴线方向、坝头位置及丁坝间距等。重要河段的丁坝布设，应根据水工模型试验确定。丁坝建成运用后，须经常进行观测，看其是否稳定，是否达到预期目的，必要时，加以调整。(汪天翔网文会)
