Abstract Research purposes ： Railway integrated alignment design is the important and difficult point for the project， and it is directly related to the reliability and economy of project construction. Through the analysis of high geothermal distribution of Lhasa - Rikaze Railway and the harmfulness influences on the project， the railway alignment principles and design concepts of geothermal district have been proposed in the paper， as well as the geothermal integrated solutions. These are valuable for popularization and application on integrated alignment design and engineering construction of geothermal anomaly district in future.
Research conclusions ： (1) According to the influence degree of the geothermal harm on the tunnels construction and operation，the geothermal temperature of Lhasa - Rikaze Railway tunnels is divided into 5 levels. (2) The geothermal will affect tunnel project on the construction environment，the efficiency of construction，the selection of building materials， structure safety and operation maintenance and so on. ( 3 ) By the summary and analysis of geothermal project， the railway alignment principles and concepts of 11 first open line， shallow tunnel depth， high line location11 should be insisted. (4) When the railway across geothermal area， firstly it is necessary to take fully account of the geothermal problems in design， secondly it is necessary to organize geological forecast work well in advance， meanwhile it is necessary to apply scientific and reasonable engineering measures. (5) By the integrated research on geothemal project， the design principles and concepts of railway alignment are proposed，，the results have great value to reference for similar projects.

Key words： Lhasa - Rikaze Railway geothemal integrated alignment design
