上海轨道交通2号线东延伸段与磁浮线路并行方案的优化与评估

Evaluation and Optimization of the Scheme on Paralleled Lines of Rail Transit and Maglev

近年来,进入磁浮线安全保护区的工程项目越来越多。高速磁浮系统运行对线路轨道变形的要求较高,因此需对临近高速磁浮线路、后期实施的工程项目方案进行优选和评估分析,从而保障磁浮线的安全运营。结合上海轨道交通2号线东延伸工程,对其在浦东国际机场段线路与磁浮线并行段工程方案进行了优化研究,并采用数值分析方法就轨道交通实施对磁浮线路的影响进行了分析评估。最后通过实测数据验证了前期工程方案优化和评估方法的合理性。

Recently, more and more projects have entered into the security zone of maglev line. New projects constructed after the maglev line must be evaluated to ensure the safe operation of maglev train because of the strictly requirements on rail distortion of maglev line. Shanghai metro Line 2 is planned to stretch eastward to Pudong International Airport, this project is closely parallel to the high-speed maglev line at the engineering site where two landscape ponds of Pudong International Airport are constructed. The engineering solutions of near par- alleled section are optimized and researched in this paper, the construction effect to maglev line is analyzed by using FEM method, and the rationality of previous solutions and evaluation method have been verified according to the measured data in the end.
