自五号线开通以来,入段线磨耗截止2011年6月10日发展到13.39mm,动物园至杨箕的磨耗也已超过9mm。如何降低目前的发展速度,将是小半径曲线磨耗的养护及减轻曲线病害的主要工作。小半径曲线换轨必须考虑五号线的施工环境和工程特点,做好应有的施工组织方案及应急预案。 Since the opening of the 5th line, the entry line wear and tear as of June 10, 2011 to 13.39mm, the zoo to Yangui wear has more than 9mm. How to reduce the current pace of development will be the main work of conservation and curve lessening of the curve of small radius. Small radius curve change must take into account the construction line of the 5th line and engineering characteristics, do a good job of the construction organization and contingency plans.
