摘　　要：大丽攀铁路引入大理枢纽工程中,需要改建楚大铁路并将其引入新建的大理北站,在改建过程中楚大铁路不可避免地与大丽高速公路连接线产生交叉。为确保改建方案科学合理、工程投资造价可控,本文重点对交叉方案的合理选取进行研究。通过对线路走向、坡度、安全因素以及社会影响等方面的综合比选,得到合理的交叉方案,并针对该交叉方案提出了安全的工程措施与施工方法。研究成果可为类似铁路与公路的交叉方案选取以及工程措施提供一定的参考和借鉴。In the Dali-Lijiang-Panzhihua Railway project connecting to the Dali hub,the existing Chuxiong-Dali Railway needs to be reconstructed and diverted to the newly built Dali North Station.During the reconstruction,the railway inevitably intersects with the Dali-Lijiang Expressway connection line.To ensure a scientifically sound and cost-effective reconstruction plan,this paper focuses on the rational selection of the crossing scheme.Through a comprehensive comparison of such factors as route alignment,gradient,safety considerations and social impact,an optimal scheme was determined.Additionally,corresponding safety engineering measures and construction methods were proposed for the selected scheme.The research findings can provide valuable references for similar railway-highway crossing schemes and engineering practices.
