摘要
采用"线形相近、基本平行"原则,对比了三种结构层调坡方案的技术效果及经济性,确定在施工过程中采用"一次挂线滤波、二次挂线调坡"的方案,依托实体工程进行平整度控制。
This paper compares the technical and econ - my effect of three gradient adjusting alternatives and adopts the hanging line method for one time smoothing and then adjusting gradient. Test results of field - testing project indicates that evenness modification effect could be transfer layer by layer. This paper also proposes the systematic technical specifications for evenness control.
