摘要:
针对一曲线连续箱梁桥,分别设计了全抗扭跨支承和两端抗扭、中间跨独柱墩支承两种方案,从弯矩、剪力、扭矩和支座反力等方面对比分析了各自的受力特点;对独柱墩支承形式还设计了支座偏心,以进一步探讨独柱墩曲线梁桥的受力性能.结果表明,通过设置支座偏心,可以在很大程度上克服两端抗扭、中间跨独柱墩支承曲线梁桥的缺点,其受力性能可以满足工程应用要求.
Abstract:
With regard to a curved continuous bridge with box girder ， two supporting systems were respectivelydesigned，namely ，torsion-resist supports at all supports and torsion-resist supports only at both end supports ,single supports at all middle span supports，and comparative analysis has been conducted on their mechanicalproperties from moment，shear forces，torque and support reaction forces. Bearing eccentricity has been takeninto consideration in this paper，in order to investigate the mechanical properties of curved girder bridge withsingle supports at all middle spans further. Calculation results show that if applicable bearing eccentricity is setup， the disadvantages of curved girder bridge with single supports at all middle spans could be overcome，andits mechanical properties can still meet the requirements of engineering application.
