本文简介了南盘江天生桥二级水电站引水隧洞施工组织设计的要点,并通过施工实践的再认识,从实用的角度出发,对大型长水工隧洞施工组织设计工作要素进行了较系统的剖析和总结。具体分析按如下几个方面进行:(1)洞线布置方案比较中考虑的施工因素;(2)两条平行主洞组成同一个施工系统的施工程序;(3)洞室开北的施工;(4)混凝土衬砌施工等。本文还对大型长水工隧洞施工组织设计的任务及特点进行了总结。
This article briefly introduces the key points of the construction design of the diversion tunnel of the Tianshengqiao Ⅱ Hydropower Station in Nanpanjiang River Basin. Through the re-understanding of construction practice, from a practical point of view, to sum up. The detailed analysis is carried out according to the following aspects: (1) Construction factors considered in the comparison of layout of cave lines; (2) Construction procedures of two identical main tunnels forming the same construction system; (3) (4) Concrete lining construction and so on. This article also summarizes the tasks and characteristics of the construction of large long hydraulic tunnel construction.
