摘　　要：整体式箱梁桥偏载系数的简化计算及近似取值,是桥梁工程技术人员经常遇到的主要问题之一。以5座整体式不同桥宽、等截面的连续箱梁桥为研究对象,通过静力加载试验,对偏载加载工况实测挠度数据进行统计分析,基于实测荷载偏载系数,得出其特点及分布规律,为同类桥梁的检测设计提供依据。Taking five integral continuous box beam bridges with different bridge widths and equal cross sections as the research objects, through the static load test, this paper statistically analyzed the measured deflection data of partial load loading conditions. Based on the measured partial load coefficient, it also obtained its characteristics and distribution law, which provided the basis for the test design of similar bridge.
