摘要:
基于江苏全省高速公路桥梁逾5.4×107辆汽车荷载数据,统计全省高速公路桥梁汽车荷载特性,包括车型、车身质量、车间距、轴质量、轴间距等,建立全省高速公路汽车荷载特性的概率分布模型.然后,采用与国家规范制定相似的流程和方法,建立江苏省高速公路桥梁汽车荷载模型,并计算模型的相关系数.结果表明,江苏省高速公路桥梁两轴车和六轴车比例分别约为76%和15%,平均超载率为7%.江苏省高速公路桥梁的实际运行汽车荷载为规范中公路-Ⅰ级汽车荷载中车道荷载的1.46倍.根据实测汽车荷载数据,计算得到一车道、二车道、三车道、四车道、五车道、六车道的横向折减系数分别为1.20、1.00、0.85、0.72、0.60、0.47.研究结果可为江苏省高速公路桥梁汽车荷载标准的制定及既有桥梁加固维修提供参考.
Abstract:
Based on the vehicle load data of more than 54 million vehicles of highway bridges in Jiangsu province, the characteristics of the vehicle loads were analyzed statistically, including vehicle type, weight, vehicle distance, axle load, axle spacing and so on. The probability distribution models of the characteristics of the vehicle load of highway bridges in Jiangsu province were established. Then, by using the processes and methods similar to those of in national vehicle standard, the vehicle load model of highway bridges in Jiangsu province was put forward, and the correlation coefficients were calculated. The results show that the proportions of 2-axle and 6-axle vehicles an highway bridges in Jiangsu province are about 76% and 15%, respectively, and the average overload rate is 7%. The actual vehicle load on highway bridge in Jiangsu province is 1.46 times that of the grade Ⅰ vehicle load of current China’s specification. The transverse reduction factors calculated from the vehicle load data for one to six lanes are 1.20, 1.00, 0.85, 0.72, 0.60 and 0.47, respectively. The results can provide references for the establishment of the standard of vehicle loads as well as the maintenance and strengthening of existing bridges in Jiangsu province highway.
