湿陷性黄土地区铁路站场路基排水设计

Design of Subgrade Drainage in Railway Station Yard of Collapsed Loess Area

针对湿陷性黄土对工程易造成湿陷沉降等危害的特性,提出在铁路站场排水设计中采取相应的工程措施,避免线路建成后发生湿陷沉降危害。通过阐述填方站场路基排水设计、路堑站场路基排水设计和车站综合排水设计的具体措施,分析湿陷性黄土对工程建设的危害,在设计中应注重加强铁路站场路基的稳定性。

Targeting with the characteristics of collapsed loess on causing engineering collapsed settlement, this paper puts forward corresponding engineering measures should be applied on drainage design of railway station yard as to avoid the collapsed settlement harm after railway line construction. Through expounding the detailed measures on subgrade drainage design of filling yard and cutting yard as well as comprehensive drainage design of station, the paper analyzes the harm of collapsed loess on engineering construction, and puts forward the design should pay attention on strengthening the subgrade stability of railway station yard.
