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<21.5°~34°时,抗倾覆稳定系数趋于稳定。
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.
