交通量对高速公路桥梁承载力的影响研究

Study of the Influence of Traffic on the Bearing Capacity of Highway Bridges

本次试验是国内首次通过大规模交通量统计、精确标准轴次当量换算以及修补加固情况调查来选定高速公路钢筋混凝土梁桥,并对其进行现场承载力试验,研究了交通量对高速公路桥梁承载力的影响,结果表明:大交通量并未对桥梁的承载力造成明显的影响,但会对桥体结构造成一定损伤.

This research conducts the first experiment in China to select a highway reinforced concrete girder bridge with large-scale traffic statistics,precise standard axle load equivalent conversions,repairing and strengthening investigations,and carries out a bearing capacity field test to research the influence of traffic on highway bridges. The results show that the large traffic does not obviously affect the bearing capacity of the bridge,but it can cause some damage to the structure of the bridge.
