摘要
NT1水电站主要特点为洪水流量巨大,装机相对较小,泄洪、导流建筑物规模大。可研阶段泄水建筑物投资占整个建筑工程投资的比重高。为了降低工程投资,通过对导流洞改建为泄洪洞,以及放空洞和导流洞、泄洪洞结合的可能性进行分析研究,并采取了大坝旁设置正常溢洪道和非常溢洪道相结合的方案,解决了洪水期大流量泄洪问题,降低了工程投资,有利于工程的推进。
The main characteristics of NT1 hydropower station are huge flood discharge,relatively small installation,large scale of flood discharge and diversion buildings. The investment of flood discharge buildings in the feasibility stage is higher than that of the whole construction project. In order to reduce the project investment,the reconstruction of diversion tunnel for flood discharging tunnel,and put the empty and the diversion tunnel,flood discharging tunnel combined for analysis and research,normal spillway and emergency spillway are located near by the dam,solved the problem of flood period,reduce the engineering investment,conducive to advancing engineering.
