摘要
伴随高速铁路快速发展,越来越多建设项目遇到邻近运营高铁路基设计及施工问题。高速铁路运营对路基变形要求非常高,邻近其设计、施工存在较大困难及风险。本文通过对高速公路加宽、普速铁路复线工程等进行调研,同时结合连镇高铁引入运营沪宁高铁镇江站工程课题研究结果,提出几种邻近运营高铁路基设计方案,并进行多方案对比分析,给出一些邻近运营高铁路基设计合理建议。
With the rapid development of China’s high-speed railway,more and more projects encounter the problems of subgrade design and construction near the operation of high-speed railway.There is a high demand for deformation while operating the high-speed railway,and there are great difficulties and risks in its design and construction.Based on the investigation of expressway widening and common speed railway double track project,and combined with the subject research results of the introduction of Lianyungang-Zhenjiang High-speed Railway into Zhenjiang Station of Shanghai-Nanjing High-Speed Railway,this paper puts forward some subgrade design schemes close to the operation of high-speed railway,conducts a comparative analysis of several schemes,and provides some rational suggestions on subgrade design of adjacent operating high-speed railway.
