王瑶水库泄洪洞工程为该水利枢纽主要建筑物之一。隧洞全长740米,由压力洞、无压洞及进出口段组成。控制泄流的是放水塔,塔高60.5米。洞子最大宣泄流量为79米~3/秒。洞轴线主要穿过硅质页岩、泥灰岩、混岩、沙质泥岩及细沙岩等五种岩层,均属侏罗系安定组(J)岩层,普氐系数f=3～4。上复岩层最大厚度19米,最薄为3米。基岩以上覆盖第四纪黄土,最大厚度为90米,最小为5米。洞身围岩大部分岩石比较完整,从表面
Wangyao reservoir spillway tunnel project is one of the major structures of the water control project. The tunnel is 740 meters in length and consists of a pressure tunnel, a pressureless tunnel, and an entrance and exit section. Control discharge is the water tower, tower 60.5 meters high. The largest cave vent flow 79 meters ~ 3 / second. The cave axis mainly crosses five types of siliceous shale, marl, mixed rock, sandy mudstone and fine sandstone, which belong to the Jurong Formation (J) rock formation with a normal Pu = 3 ~ 4. On the maximum thickness of 19 meters, the thinnest is 3 meters. Quaternary loess over the bedrock, the maximum thickness of 90 meters, a minimum of 5 meters. Most of the rock around the rock is relatively complete, from the surface
