| 摘 要： | 按Ｒｉｔｚ法求得铰支和固支圆拱受静水压力作用时，具有高精度的正对称失稳临界力的第３次近似值。在圆拱临界力的求解中，还可同时导得圆环以不同波数失稳的临界力的精确值。

| Abstract: | By means of Ritz method, the cubic approximation of the symmetric critical destabilization load is obtained for the circular arch with articulated and fixed support under hydraulic pressure. In the calculation of the critical load for the circular arch, the accurate value of the destabilization load for the ring can be determined on the basis of different wave numbers. |
