引入一个弯沉盆修正系数来考虑贝克曼梁支点和百分表支架处竖向位移对测点弯沉的影响。分析了双层路面结构的弯沉盆修正系数变化规律 ,建立了弯沉盆修正系数与路面结构整体刚度之间的回归关系
A correction coefficient of deflection bowl is introduced to consider the effect of vertical displacement of Beckerman beam fulcrum and dial indicator bracket on deflection of measuring point. The variation law of the correction coefficient of the deflection basin of the double-pavement structure is analyzed, and the regression relationship between the correction coefficient of the deflection basin and the overall stiffness of the pavement structure is established
