摘　　要：新建铁路与运营高速铁路衔接时,在引入既有车站且受限地段,必须控制营业线路基附加变形和确保运营安全。以新建商丘至合肥至杭州高铁接入既有车站为工程背景,阐述新建线路在不同条件下不同类型受限地段的路基工程设计、施工方案,目前国内尚处于探索与积累经验阶段,对其采用的综合加固处理设计及施工方案,解决了新建高铁引入既有车站受限地段施工时,对运营高铁产生不利影响的问题。现场施工表明,设计方案合理,效果良好。When new railways are connected to existing operating high-speed railways,it is necessary to control the additional deformation of the subgrade of the business lines and ensure the operation safety of the lines in the process of connection to existing stations on restricted sections.In this paper,the connection of newly constructed Shangqiu-Hefei-Hangzhou High-speed Railway to existing station(s)is taken as an example.During the construction of the new line,the subgrade works in different restricted sections under different conditions are reviewed with respect to the design and construction scheme of comprehensive reinforcement treatment,aiming to solve the problems that the operating high-speed railway will be adversely affected when new railways are connected to existing stations on restricted sections.The construction in the field indicates that the design scheme is reasonable and effective.
