摘要
百色水利枢纽 3B坝段孔洞密集 ,且在空间位置上相互交错。为此 ,采用三维有限元数学模型对 3B坝段坝身孔、洞进行应力应变分析 ,定量分析了各工况下坝体孔、洞周边的应力应变量值及分布特征 ,评价了坝体应力的安全性 ,为孔。
B dam block of Baise main dam is designed with dense and space intersecting caverns. The stress and strain around the holes or caverns in the 3B dam block is analyzed with a three-dimensional finite element mathematical model. The stress-strain values and distribution features under various operating conditions is quantificationally analyzed, and the safety of dam body in respect of stress is also assessed, which provide the basis for the design of reinforcement around holes or caverns.
