摘要
为满足观景口水利枢纽工程截流进度要求,缩短导流洞施工工期,对右岸导流洞线路布置进行了设计优化,根据地形地质条件,通过深入研究临时建筑物导流洞与永久建筑物溢洪道空间布置关系及其运行时段要求,尽可能将右岸导流洞进、出口位置向坝轴线平移靠近,缩短洞线长度,充分利用导流洞与溢洪道运行时段相互独立的特点,使导流洞后段从溢洪道泄槽底板的岩层中穿过。布置优化后导流洞洞线长度由700 m缩短至350 m,工期由11个月缩短至5个月。目前工程运行状况良好,导流洞布置设计优化成效显著。
In order to meet the schedule of damming of the Guanjingkou Reservoir and shorten the construction period of diversion tunnel,the design is optimized for the general layout of diversion tunnel on the right bank.According to topographical and geological conditions,in-depth studies have been made on the relationship between spatial layout of diversion tunnel of temporary buildings and spillway of permanent structures,as well as operation period requirement.The positions of inlet and exit of the diversion tunnel on the right bank are placed to the dam axis as close as possible,so as to shorten the tunnel line length,and make full use of the independent operation period of the diversion tunnel and allow the rear section of diversion tunnel pass through the rock stratum of bottom plate of the spillway chute.As a result,the length of diversion tunnel line shortened from 700 to 350 meters,and the construction period reduced from 11 to 5 months.Currently the dam is under good operation condition and the optimization of design produces a marked effect.
