摘要
采用二维非线性有限元分析方法,对六库水电站RCC纵向围堰防渗墙的防渗效果和应力应变状态进行了研究,在此基础上对防渗墙各截面的剪力、轴力和弯矩进行计算研究,提出了配筋方案。计算表明,防渗墙的防渗效果显著,分载作用明显,右防渗墙承受的弯矩更大些,应加大其配筋率。
The paper has made a study of impervious effect and stress-strain condition of the RCC longitudinal cofferdam impervious walls in construction of the Liuku hydropower project using two-dimensional non-linear definite element analysis method and put forward reinforcement scheme according to the calculation and study results of shear, axial force and bending moment of various cross sections of the impervious walls. The calculation indicates that the impervious walls produce significant impervious effects and proper load distribution effects, and the right impervious wall bears a bit more bending moment, which requires increase of ratio of reinforcement.
