曲线桥梁抗倾覆稳定参数分析

Analysis on Anti-overturning Stability Parameters of Curved Bridge

摘要:

通过参数分析，探讨曲线桥梁支座布置、平面圆心角和曲率半径对其抗倾覆稳定的影响。结果表明：中墩采用双支座、减少单联桥梁圆心角，能有效改善曲线桥梁的抗倾覆稳定性能；当圆心角φ<34°时，抗倾覆稳定系数趋于稳定。

Abstract:

Based on the parameter analysis, the influence of support layout, plane central angle and curvature radius of curved bridge on its anti-overturning stability is discussed. The result shows that the adoption of double support and the reduction of single-bridge central angle of the middle pier can effectively improve the anti-overturning stability of curved bridge. When the central angle φ<21.5°~34°, the anti-overturning stability coefficient tends to stabilize.
