引水隧洞引水隧洞diversion tunnely一nshu一su一dong引水隧洞(diversion tunnel)在山体内开挖成的引水道。按洞内水流有无自由水面，引水隧洞分无压和有压两种。选择洞线时一般要求便于上下游水流衔接，洞线短，转弯少，并便于布置施工支洞，同时尽可能地要求其通过的岩体地质构造简单，岩体完整稳定，地下水位低。为综合满足以上要求，洞线常为曲折状。其断面尺寸由技术经济比较决定。一般，先假定几个隧洞断面尺寸方案，计算其水头损失、出力损失和年电能损失。将各方案的一次投资和正常运行期的年运行费按复利折算到某一基准年，选用计算期内总费用最小的方案。其纵向坡度一般在1%。~5编范围内。无压引水隧洞断面形状多为圆拱直墙型或马蹄型，见图l。其断面高宽比一般为1一1.5。在岩石侧压力小或水位变化较大时，可选择较高的断面。水面至洞顶要留有一定的空间，以避免明、满流交替。粼合图1无压引水隧洞断面实例 (a)国拱直培型;(b)马蹄型1一混凝土;2一钢筋混凝土;3一受力钢筋有压引水隧洞断面形状一般为圆形，见图2。其承受内、外水压力的性能较好，湿周短，水头损失小。个必 图2有压引水隧洞衬砌(a)混凝土的衬砌;(b)钢筋混凝土的衬砌 1一混凝土;2一钢筋混凝土;3一环形受力钢筋隧洞衬砌引水隧洞重要的组成部分。其作用是承担内、外水压力和山岩压力、减小渗水、防止岩体崩塌和降低糙率。除岩体坚硬、致密和完整的地段外，一般都要做衬砌，主要有混凝土、钢筋混凝土和喷锚3种衬砌类型，此外还有预应力混凝土衬砌，见图l、图2。当围岩较完整，内水压力不大时，可采用混凝土衬砌;当内水压力较大，围岩较差时.应采用钢筋混凝土衬砌;当围岩完整，渗透性小，可把围岩视为受力结构.不做衬砌或采用喷锚衬砌。预应力混凝土衬砌具有较高的承受内水压力的能力，这种衬砌可节约钢材，降低造价。中国白山水电站1号引水隧洞洞径8.6m，首次采用了灌浆式预应力混凝土衬砌，已安全运行了。隔河岩水电站引水隧洞洞径9.sm，采用了后张法预应力混凝土衬砌，运行情况良好。小浪底工程的排沙洞洞径6.6m，最大运行水头125 m.也采用了后张法预应力混凝土衬砌。衬砌常设纵横缝，纵缝一般都设键槽和插筋，横缝通常只设施工缝，在地质条件明显变化处宜设伸缩缝。衬砌与岩石之间必须做回填灌桨，可做排水。围岩中是否要做固结灌泉，视其地质条件和运行条件确定。
