用平面线弹性有限元法对某重力坝坝内底孔进行了应力计算,在横剖面计算中近似地采用了纵剖面的应力成果。计算结果与通常采用的两种手算方法作了对比。粗略地估算了永久运行期的温变应力,证明其数值不可忽视。
The stress of the bottom hole of a gravity dam is calculated by the plane elastic finite element method. The stress results of the longitudinal section are adopted approximately in the calculation of the cross section. The calculation results are compared with the two commonly used manual methods. Roughly estimate the temperature during permanent operation of the stress, that its value can not be ignored.
