巴朗山隧道隧址与轴线方案研究

摘要

根据巴朗山隧道项目的技术经济条件，综合地形、地质、气象、环保和经济等因素，对巴朗山隧道的隧址和隧道轴线进行论证和比选，论证结果表明，影响隧址和隧道轴线方案的主要因素按重要性依次为地形、环保、原路改善程度、经济、地质和气象。%According to Balangshan tunnel project technology economy conditions,the article takes comprehensive topography,geology,climate, environment protection and economy into consideration,and discusses and compares Balangshan tunnel location and axial trace. Results show that:major factors influencing tunnel location and axial trace scheme include topography,environment protection,original highway improvement degree,economy,geology and climate.
