坝区泥沙淤积坝区泥沙淤积sedimentation in dam area boqLJ rl}sho ytljl坝区泥沙淤积(Sedimentation in dam area)河流上筑坝塑水后，由于塑水区内水深加大，流速降低，泥沙沿程淤积，并向坝前推进，造成坝前泥沙的淤积。坝区泥沙淤积产生的问题主要有:①在船闸引航道中及其口门附近产生淤积，使航深不足或水流不顺而有碍通航。②电站进水口前的泥沙堆积使过机水流中的含沙量增大，泥沙变粗，造成过水建筑物或水轮机过流部件的严重磨损。③坝前泥沙淤积有可能影响问门启闭，堵塞泄水孔，影响大坝安全。 以通航为主的枢纽和以发电为主的枢纽对坝区水流条件的要求不同，防治坝区泥沙淤积的措施也不一样。 (1)以通航为主的枢纽。宜将船闸布置在靠近稳定深乱线一侧，要避开弯道的凸岸和回流、缓流区。这些地区都是泥沙集中淤积处，且淤积后又难于冲走。结合各个工程的实际情况，可设置某些导流排沙工程，如修建引航导墙以破除回流减少淤积;设置底部高程较低的冲沙闸，以定期冲刷上游及下游引航道淤沙。 (2)以发电为主的枢纽。高水头水电站的防沙措施主要是设置高程较低的排沙孔。排沙孔布置在机组进水口的下面，防沙效果最好，但结构复杂，施工及管理都不便。一般把排沙孔设在进水口的侧下方，其位置以使进水口处在冲刷漏斗的影响范围之内为原则。低水头枢纽的防沙措施，主要是进行合理的平面布置。如利用弯道环流特性，正面取水，侧面排沙，同时设置导沙坎，常能取得较好的防沙效果。在中小型水库中，也可采取清浑水分治的办法，即在童水区上游修建排浑渠(或排浑洞)，当汛期洪水人库时，可将浑水通过排浑渠(洞)直接排往坝下游，减少主库淤积，缓解坝区泥沙问题。
