摘　　要：在高速公路的改扩建过程中,由于路基拓宽,新老路基结合引起的路基路面变形、开裂问题十分普遍,对高速公路路基加宽工程的主要病害和破坏机理进行了详细地分析,指出新老路基之间的不良结合和不均匀变形是最根本的原因,讨论了新老路基结合部的处治技术。The phenomenon of deflections and cracks are very prevalent in new and existing embankments during the course of highway reconstruction o On the basis of failure mechanism of joint of the old and new embankments , the results show that the badness combined and differential settlement are the major one in the highway widening engineering. At last,The treatment techniques are discussed andthe experiences in design and construction in highway widening engineering are given.

关 键 词：高速公路 路基加宽 相互作用 处治技术
