城市轨道交通调线调坡方法研究

摘要

分析了引起城市轨道交通调线调坡的原因，提出了城市轨道交通调线调坡的测量要求及设计方法。以长沙市轨道交通2号线一期工程为例进行了调线调坡设计验证，总结了调线调坡及线路设计应注意的问题。%The paper analyzed causes for the urban rail transit adjustment of alignments and gradient, proposed the measurement requirements and the design methods of adjusting alignments and gradient. Taking the first-stage construction of Changsha urban rail transit number 2 line as an example,the pa-per verified the design of adjusting alignments and gradient,finally summarized some problems en-countered in the process of adjusting alignment,gradient and line design.
