本文针对变跨等截面连续梁桥,以边主跨比为参数建立不同跨径的模型计算冲击系数,并根据计算结果对该类桥型的影响参数进行了拟合分析,对将来常规连续梁桥冲击系数的具体化计算起到一定的参考作用。
In this paper, the cross-section continuous girder bridge with different span-span ratio is taken as the parameter to build the model with different span diameters to calculate the impact coefficient. According to the calculation results, the influence parameters of this kind of bridge type are fitted and analyzed. The concrete calculation of bridge impact coefficient plays a certain reference role.
