介绍武广客运专线过渡段路基的本体强度、刚度过渡和地基沉降过渡的设计,提出客运专线过渡段路基设计不仅要根据地基条件、填筑材料及压实程度等方面进行过渡段的刚度与变形协调设计,针对相邻结构物间短路基的长度过短,存在动应力与动变形相互叠加,设计了“组合型”过渡段路基。 This paper introduces the design of body strength, stiffness transition and foundation settlement transition of the transitional section of Wuhan-Guangzhou Passenger Dedicated Line. It is proposed that the design of subgrade of transitional section of passenger dedicated line should not only be based on the foundation conditions, filling materials and compaction degree, In the coordinated design, aiming at the short length of shorting base between adjacent structures, the dynamic stress and dynamic deformation are superimposed on each other, and the “combined type” transitional subgrade is designed.
