摘　　要：大厚度水泥碎石分层施工时不同施工方法导致层间结合状态介于完全连续和连续光滑。根据FWD实测数据计算得到的层间结合系数,通过引入弯沉计算系数,计算不同结合状态下的路表弯沉;最终通过铺筑试验路,验证计算方法的可靠性。The different construction methods result in different state of interlayer between completely continuous and continuous smooth during the construction of the large thickness cement stone layer.Based on the measured data calculated FWD interlayer bonding coefficient,the road surface deflection was calculated under different binding state by introducing the coefficient of deflection in this article;finally the reliability of calculation methods was verified by the test road paving.
