摘要:
日兰高速铁路联络线引入既有京沪高速铁路曲阜东站，线间距仅6.5m，对侧新建高速铁路场，线间距20m，新建铁路对既有高速铁路沉降变形将产生严重影响。本文以该项目路基工程为依托，结合实施工期、安全、经济及技术等指标进行综合比选，通过加强现场试桩及监测，最终在联络线引入路基工程采用桩板+悬臂式挡土墙、轻质混凝土结构，对侧高速铁路场采用CFG桩+扶壁式挡土墙路基结构，以减少新建铁路施工对现有高速铁路的影响。研究成果可为临近高速铁路地基加固提供参考借鉴。
Abstract:
The feeder line of Rizhao-Lankao High-speed Railway is connected to Qufu East Railway Station of the existing Beijing-Shanghai High-Speed Railway，with a line spacing of only 6. 5 m. A new high-speed railway yard is constructed on the opposite side with a line spacing of 20 m. The new railway will have a significant impact on the settlement and deformation of the existing high-speed railway. For the construction of subgrade for this line，this paper comprehensively compared multiple optional structure schemes in terms of indicators such as construction period，safety，economy，and technology. Through reviews at stages，adding on-site pile testing and close monitoring，the piled-raft foundation with cantilever retaining wall and lightweight concrete structure was ultimately adopted for the subgrade of the feeder line，while a CFG pile with a retaining wall structure was implemented for the opposite high-speed railway yard. This approach aims to minimize the impact of constructing new railway on Beijing-Shanghai High-speed Railway. The research results can provide reference for similiar foundation reinforcement of the adjacent high-speef railway.
