摘要
提出了引兰入汤输水隧洞输水能力复核及隧洞原型观测的必要性;介绍了该工程的概况;通过原型观测的各数据得出了隧洞的实际糙率,实际糙率较设计糙率小;对实际糙率与设计糙率进行了比较分析,并对隧洞过流能力进行了复核。
This paper puts forward necessity of original observation of roughness and checking water carrying capability for water diversion tunnel from Lan river to Tanghe reservoir; this paper educes actual roughness by original observation, compares actual roughness with designing roughness and checks water carrying capability for water diversion tunnel.
