摘要
采用三维有限元方法,分析了大花水碾压混凝土拱坝的应力、变形,比较了无诱导缝和设诱导缝对大花水拱坝坝体应力、应变规律的影响。论证了诱导缝设置位置的合理性,并提出设置周边缝的合理范围,为工程设计提出依据和建议。
In this paper, the distribution characteristics of stress and deformation of the Dahuashui RCC arch dam are analyzed by using 3-D FEM. Based on the analysis, the influences of the non-induced joint and induced joint on the rules of stress and deformation of the dam are evaluated. According to the study, the rationality for the position of the induced joint is justified, the best location for setting peripheral short joint is given out, and some proposals for design and construction are put forward.
