简支梁桥面连续板桥国内外应用日益普遍。其荷载横向分布研究如何计算,以往我们尚缺乏依据。通过荷载试验,实测梁的转角及挠度与简支梁体系完全相同,说明连续桥面相对刚度较小,它仍属简支体系,其荷载横向分布可按简支体系计算。对于宽桥而言,按刚接梁桥实用表格法和G—M法计算均偏于完全,可供计算应用,而按法计算,则不够安全,故不宜采用。
The application of simply supported girder deck continuous slab bridge is increasingly widespread at home and abroad. How to calculate the horizontal distribution of its load, in the past we still lack a basis. Through the load test, the measured angle and deflection of the beam are exactly the same as that of the simply supported beam system, which shows that the relative stiffness of the continuous deck is small. It is still a simple supported system, and its lateral load distribution can be calculated according to the simple supported system. For wide bridges, according to the just-connected girder bridge practical table method and the G-M method are both partial to the calculation, the calculation, according to the law, it is not safe enough, it is not appropriate.
