补充资料：截流
| 截流 river closure 堵截河水迫使其流向预定通道的工程措施。向流水中抛投料物填筑戗堤的工作称进占。两岸进占后预留的河道泄流口门称龙口。为防止龙口河床和戗堤端部被冲刷毁坏，需要对龙口范围内进行防冲加固。闭合龙口，最终拦断水流的过程称合龙。合龙后在戗堤迎水面采取防渗措施封堵渗漏通道称闭气。截流是水利工程施工中的关键项目，有一定风险 ，需周密计划、充分准备，要有足够的抛投强度和现场统一指挥。中国历史上，利用土石、秸料、柳枝等当地材料进行堤防堵口及截流，具有丰富的经验。现代截流工程多使用大块石和混凝土异形体等材料，利用大型自卸汽车及推土机施工。截流抛投方式可分立堵、平堵和平立堵。立堵是由龙口一端向另一端或从两端向龙口同时抛投进占，逐渐束窄龙口直至合龙。施工较简单，但龙口单宽流量大、流速高，场地狭窄，抛投强度受限制，难度较大。因此，也可采用上下游双戗或多戗堤进占的立堵方式，使落差分散，减少截流难度。平堵是在龙口架设浮桥、栈桥或其他跨河设施，沿龙口全线逐层均匀抛投料物，直至戗堤露出水面。其水力学条件较好，料物重量较小，施工场面宽阔，抛投强度高，但投资多，准备工作量大。平立堵是二者的结合，先立堵、后架桥平堵。中国至今为止截流规模最大的是长江葛洲坝水利枢纽于1981年1月进行的大江截流，截流流量4800米3／秒，最大落差3.23米，最大流速7米／秒，日最大抛投强度7.2万米3，截流历时36小时23分。 |
