飞来峡水利枢纽溢流坝应力三维有限元分析

摘要

3-D finite element method is adopted to simulate 17# block, which is the highest block of overflow dam in Feilaixia water conservancy project .The tensile stress and compressive stress value of the whole block under five working conditions are calculated out .By comparing the maximum stress value of the simulated stress with the control stress value of the specification , the results show that the stress condition of the overflow dam meets the requirements of the specification .%对飞来峡水利枢纽溢流坝坝高最大的17＃坝段，采用三维有限元法，分5个工况分别计算出整个坝段拉应力和压应力值，将各典型剖面最大的应力值与规范允许的应力控制值进行对比分析，得出了坝体应力状况满足规范要求的结论。
