Abstract
With the acceleration of urbanization and the increasing demand for transportation infrastructure for economic development,highways,as an important transportation artery,and their reconstruction and expansion work has become increasingly frequent.During the reconstruction and expansion process,the design and construction of the joint between the old and new subgrade have an important impact on the long-term stability and safety of the road.Focusing on the junction between old and new roadbed in the reconstruction and expansion of highways,this paper discusses the stability calculation method by combining practical engineering cases.The research results show that the kmin value calculated by the proposed method is lower than that calculated by the internal force transfer method and the circular arc method.关键词
