本文通过有限元数值模拟、理论计算等方法对溢流坝纵向和横向应力进行计算,研究各主应力工况应力分布规律,引进材料力学方法计算溢流坝不同荷载组合下的抗滑稳定安全系数和坝基面应力,并对溢流坝段结构稳定性进行定性分析和评价,为类似工程溢流坝结构设计和施工提供数据支撑和借鉴。

The structure of the overflow dam plays an important role in the flood control of water conservancy project dams.It is very important to improve the discharge capacity of the dam. In the paper,longitudinal and lateral stress of overflow dams is calculated through finite element numerical simulation, theoretical calculation and other methods. Stress distribution laws of different main stress working conditions are studied. Material mechanics method is introduced to calculate anti-sliding stability safety coefficient and dam foundation surface stress of overflow dams under different load combinations. The structure stability of overflow dam section is qualitatively analyzed and evaluated,thereby providing data support and reference for overflow dam structure design and construction in similar projects.
