摘要
Abstract
In view of the unclear definition of subgrade settlement control indices in current highway reconstruction and expansion specifications,this paper determined the location of maximum settlement through analysis of ideal settlement basin curves and proposes a conversion formula for transverse and longitudinal slope adjustments.Taking the Beijing-Tianjin-Tanggu Expressway(Tianjin Section)reconstruction project as a case study,a calculation example demonstrating post-construction slope changes was provided.关键词
