印度尼西亚某水电站料场边坡排水系统设计

Design of Side Slope Drainage System of a Hydropower Station in Indonesia

水电工程建筑物所需填筑料或者混凝土骨料的来源一般都是开采料场。在料场边坡综合治理时,对边坡的稳定性计算和支护措施已得到了足够的重视,但是对于料场边坡范围内外的截排水沟系统设计却少有计算。根据降雨汇流特征对边坡范围内外进行了汇流分区,计算汇流流量,并对边坡的截排水沟根据地形条件进行分段水力计算,根据计算结果,在截水沟局部段增加糙条,并在出水口处设置消力池等消能实施。

The source of filling materials or concrete aggregate for hydropower engineering buildings is usually mined material yard.In the comprehensive treatment of side slope,enough attention has been paid to the stability calculation and support measures of the slope,but few calculations have been made for the design of intercepting and drainage ditch system.According to the characteristics of rainfall confluence,the confluence area inside and outside the slope range is divided,and the flow of confluence is calculated.According to the calculation results,the local section of the intercepting ditch is added with rough strips,and the stilling basin is set at the water outlet.
