摘要
利用小变形理论及ANSYS研究了均匀径向压力作用下深圆拱的平面内稳定性,算例分析表明,当深圆拱的圆心角较小时,圆拱受径向压力的稳定性高于受静水压力的稳定性,当深圆拱的圆心角较大时,圆拱受径向压力的稳定性低于受静水压力的稳定性.
The in-plane stability of a deep circular arch under uniform radial pressure is studied by using the small deformation theory solutions and the numerical solutions of the finite element software ANSYS. The application examples indicate that the stability of the arch under radial pressure is superior to that under hydrostatic pressure with small central angle and is inferior to that with a large central angle.
