双曲拱坝的累计自重应力

Accumulated Gravity Load Stresses of Double Curvature Arch Dam

通过用三维有限元方法按计划施工顺序计算了某高双曲拱坝在自重、灌浆及水压荷载下的累计应力．并研究了不同施工阶段的累计自重应力的特点及改善、利用该应力的工程措施．

By the application of 3D FEM, the accumulated stresses of a double curvature arch dam under the loads of gravity, of grouting and of hydrostatic water pressure have been calculated, according to the sequence of planned const- ruction, The characteristics of the accumulated gravity load stresses under different periods of construction and the improvement and utilization of the stresses in the engineering measures have been studied.
