文章在研究弯道变坡摊铺控制特性的基础上,选取平衡梁基准作为斜坡输入激励,通过对平衡梁的工作特性、摊铺机工作装置的滞后特性分析,确定了工作参数,并在实体工程中设置不同工况进行试验研究。结果表明:通过合理选择平衡梁参数和采取提前输入激励等措施,使铺层横坡度与下面层横坡度有很好的符合性。 Based on the study of the control characteristics of pavement changing slope pavement, the balance beam reference is selected as the input of the slope. By analyzing the working characteristics of the balance beam and the hysteresis characteristics of the paver working device, the working parameters are determined. Set different conditions in the project for experimental study. The results show that: through the reasonable choice of parameters of the balance beam and the adoption of measures such as advance input excitation, the horizontal gradient of the pavement is in good agreement with the horizontal gradient of the subsurface.
