拉日线色麦至大竹卡峡谷地段地质选线研究

Research on Geological Route Selection in Valley Zone between Semai-Dazhuca of Lhasa-Rikaze Railway

研究目的:通过对本段地形、地质条件的分析,确定线路方案的选线原则,从而为线路方案的选择和完善提供依据。研究结果:从拉日线色麦至大竹卡段地质选线来看,具有典型的高原山区河谷铁路地质选线的特点。由于独特的自然地理环境和气候特征,使线路方案具有特殊的考虑因素,我们通过分析研究,选出了一条安全、合理、经济的线路方案,为国家节省了大量的资金。

Research purposes： Through making analyses of the landform and geological conditions in the valley zone, the principle of route selection is decided for the purpose of providing basis for the route selection. Research results： The geological route selection between Semai - Dazhuca of Lhasa - Rikaze Railway has the features of route selection in plateau mountain and valley area, so it is necessary to take the unique geographic environment and climate characteristics into account in route selection. Through making analyses and doing researches, one safe, rational and feasible route program is selected, which can save much construction cost.
