The pressure tailrace tunnel of Jingpo Hu underground hydropower station is 7.8m in designed excavation diameter, has a length of more than 40m atits lower end passing through the strata of Tertiary formation which are softand liable to be weathered,and the rock surrounding the tunnel is of lowstability (Fig. 1). Shotcrete support experiment was carried out in theexperimental tunnel in July 1973. It proved that the application of shotcretefor temporary support can give good results in quickly sealing up the sur-rounding rock from weathering and in reducing the rock deformation. Theadoption of shotcrete support in such strata has also rendered economic benefitsand proved itself to be a good construction method.

镜泊湖地下水电站的圆形有压尾水隧洞出口段,设计开挖直径为7.8米,其中长40余米一段穿越软弱易风化的第三纪地层,围岩稳定性很差。1973年7月进行了试验洞的开挖和喷混凝土试验,9月开始施工。实践证明对半胶结、软弱易风化的第三纪地层采用喷混凝土加固围岩,能有效地限制围岩变形发展,具有明显的经济意义,是一种较好的施工方法。

传统的水电站水锤测流理论是建立在刚性水锤理论基础上的,而本文以弹性水锤理论研究水锤测流,并对计算方法和测试条件作出分析,提出的计算流量公式为Qo=(Fg)/l_3(S_1-(S_2/(1+m)))+(FgH_oT)/(2L)((1-m)/(1+m)).

With the regulation graph in the form of regulation surface adopted and with runoffs between adjacent intervals taken as linearly dependent as well as by taking the hydrology prediction into consideration, a mathematical model of optimal reservoir dispatching is established. The method presented has been used to work out an optimum regulation scheme for a hydropower station in Hunan Province of China and it has been found that the scheme is far superior economically to conventional ones ever used.
