阻抗式带狭长上室型调压井三维有限元应力应变分析

Stress-strain analysis of three dimensional finite element method for throttled surge saft with long and narrow upper chamber

运用三维有限元分析方法,对布仑口-公格尔水电站调压井衬砌结构及外部围岩进行了数值模拟。通过分析调压井围岩及衬砌结构在运行期的变形及力学特性,评价现有调压井在运行期的稳定性。并对支护措施的改善提了具体的建议。为阻抗式带狭长上室型调压井的设计提供了参考依据。

By using three-dimensional analysis method of FEM, the numerical simulation was conducted for the lining and surrounding rock of the surge thaft of Bulunkou - Konggur hydropower station. It evaluated the stability of the surge shaft in running stage and proposed specific recommendations to improve the stability of the supporting structure through the analysis of the lining and surrounding rock of the surge shaft stress and deformation. The result can provide a reference for the design of throttled surge shaft with long and narrow upper chamber of similar projects.
