萨扬—舒申斯克水电站消力池的护底主要用平面尺寸6.25×7.5m,最大高度约9m的混凝土块进行了修复.混凝土块垂直分缝.1986和1988年泄洪期间对混凝土块的动态位移进行了实地试验研究.当时,消力池护底结构中尚无阻止脉动压力进入垂直块间缝的设施.各混凝土块之间由动水压力和机械力相连系.动水压力连系通过块间缝腔充水,而机械力连系则通过地基,局部地也可沿垂直面实现(如沿键槽、糙面凸角的啮合作用).混凝土护底块与基岩联成整体是个复杂的系统,它具有随时间而变化的随机应力一应变状况参数.
The bottom of the tank of Sayan-Shushenskaya hydropower station is mainly repaired with concrete blocks of 6.25 × 7.5m in plane size and 9m in height. Vertical grouting of concrete blocks. Dynamics of concrete blocks during flood discharge in 1986 and 1988 Displacement of the field test and study.At that time, there is no impeding the structure of the bottom of the pool structure to prevent the pulsating pressure into the vertical gap between the concrete blocks by the hydrodynamic pressure and mechanical force linked to hydrodynamic pressure through The joints between the blocks are filled with water while the mechanical forces are connected to each other through the foundation and locally along the vertical plane (such as the engagement of the keyway and the rough surface). The concrete support block and the bedrock are complex as a whole System with random stress-strain parameters that vary over time.
