摘要
Abstract
TB hydropower station project has the characteristics of high dam height,large storage capacity,large diversion flow,and long water storage duration.Through analysis and research,the initial diversion adopts a diversion scheme of one-time riverbed interruption,soil and rock cofferdam water blocking,tunnel discharge,and year-round construction of the dam body.Due to geological conditions,the diversion tunnel is arranged on the mountain side with a longer tunnel line.Due to the large volume of flood peaks and the relatively large section of the diversion tunnel,the selection of section size directly affects the overall construction progress and investment of the project.By optimizing and analyzing the diameter of the TB diversion tunnel,the goal of accelerating progress and reducing engineering investment can be achieved.关键词
