混凝土重力坝结构断面优化设计研究

Optimal Design of Structural Section of Concrete Gravity Dam

借助ANSYS软件对重力坝的曲线断面和传统三角形断面进行优化设计,建立数学模型,求解优化设计变量,对优化结果进行分析;对曲线形式重力坝进行应力和抗滑稳定分析,并与传统三角形断面重力坝优化结果进行对比,得出与传统断面模型相比,曲线型重力坝有减少断面面积、节约材料、安全可靠等方面优势。

The ANSYS software is used to optimize the design of the curved section and traditional triangular section of the gravity dam by establishing a mathematical model,solving the optimal design variables,and analyzing the optimization results.The stress and anti-sliding stability result of the curved gravity dam is compared with the optimization results of the traditional triangular cross-section gravity dam.It is concluded that compared with traditional cross-sectional models,curved gravity dams have advantages in reducing cross-sectional area,saving materials,and being safe and reliable.
