一、前言奥矢作抽水蓄能电站工程已于1976年动工,计划于1981年建成。作为该电站上池的黑田坝系1934年建成的35米高的混凝土重力坝,现拟加高10.2米,以扩大其库容。混凝土重力坝的加高,已有许多工程实例,但黑田坝的特点是用电计算机进行运算。通过模拟计算大坝的温度分布和温度应力,求出了新老混凝土接合面的温度应力,并和实测资料进行了比较。其次,由老坝取样,对新老混凝土的结合进行了试验测定,以弄清加高坝体的整体性和安全性。
I. Introduction Austrian vector as a pumped storage power station project was started in 1976, is scheduled to be completed in 1981. Kuroda Dam, a reservoir of the station, is planning to raise the storage capacity of the 35-meter-high concrete gravity dam built in 1934 to 10.2 meters. Concrete gravity dam heightening, there are many examples of projects, but the Kuroda dam is characterized by electricity computer operation. By calculating the dam temperature distribution and temperature stress, the temperature stress of the new-old concrete joint surface was calculated and compared with the measured data. Secondly, sampling by the old dam, the combination of new and old concrete was tested to ascertain the heightened integrity and safety of the dam.
