摘    要:引子渡水电站采用长引水系统,在下游较宽敞的胡家大地平地布置发电厂房、以使发电厂房远离雾化区,从而保障良好的运行条件,同时也有利于施工、减少施工的相互干扰。引水系统线路总长1100m,采用一洞-三机供水方式,由岸塔式进水口、引水隧洞、阻抗式调压井、压力钢管等组成。该引水系统线路长、建筑物复杂、洞室围岩稳定性较差。经过对引水系统的水力过渡过程分析计算、调保计算和结构计算,满足了结构、大小波动稳定和运行的要求。

关 键 词:引水隧洞 调节保证计算 调压井 大型钢岔管 引子渡水电站 平地布置

Abstract:The Yinzidu Hydropower Station adopts long diversion system with the total length of 1100 m. Its powerhouse is arranged in the Hujiadadi flat ground that is more commodious and is favorable to the construction. The powerhouse is far away from the fog area so that it has good operation conditions. It adopts the water supply way of one tunnel for three generating units. The diversion system is composed of bank tower intake, diversion tunnel, reluctance surge shaft and penstock. The diversion system is long and its structures are complicated. The stability of the surrounding rock of the underground caverns is poor. Based on the hydraulic analysis and calculation, the regulation firm calculation and the structural calculation, the practice showed that the design meets the requirements of structure, stability and operation.
Keywords:diversion tunnel   regulation firm calculation   surge shaft   large sized steel bifurcated pipe   Yinzidu Hydropower Station
