连续不均匀厚度路面结构层高程施工控制

Elevation Construction Control for Pavement Layers with Continuous Uneven Thickness

在工程实践中,对于均匀厚度路面结构层高程的控制,普通的钢丝放样方法即可满足要求,而对于沉降等原因引起的不均匀厚度铺筑层的情况,一般的方法无论对于高程还是横坡的控制都不能达到理想的效果,有时甚至出现较大的偏离。通过对测量基础数据的系统分析,总结出不均匀厚度路面结构层高程控制的方法,并在本项目的实践中得到了很好的应用。

In engineering practice,for the elevation control of the pavement layers with uniform thickness,the general methods such as wire lofting can meet the corresponding requirements.However,for the pavement layers with uneven thickness caused by settlement or other reasons,the general methods will not achieve the desired effects in the control of neither elevation nor cross slope,sometimes even resulting in a large deviation.In this paper,through a systematic analysis of basic measurement data,the elevation control methods for the pavement layers with uneven thickness are summarized and well applied in the practice of the project.
