摘　　要：随着铁路建设的快速发展,不但新线建设突飞猛进,而且既有线扩能改造和复线建设也在逐步加快。这样以来,临近动车营业线的施工时有发生。为确保动车的运行安全,需采取施工安全防护措施,不仅降低了施工效率,还增加了行车干扰费。此文以遂渝二线临近动车营业线施工为例,阐述了可采取的几种安全施工防护措施,并对所引起的施工增加费进行了测算。结果表明,所占比例达到初步设计批复概算的3.32%,应引起足够的重视。With rapid development of railway construction, not only the construction of newly bulit railway makes a spurt of progress, but also the construction of capacity expansion revamping and newly built second railway line has gradually accelerated. In this way, the railway construction near EMU operation line happens sometimes. In order to ensure the safety operation of EMU train, the safety precautions should be taken. But the safety precautions reduce construction efficiency, and increase traffic interference charges. Taking the construction of Sui - Yu railway second - line near EMU operation Line as example, several protective measures can be taken are expounded, and the increased cost is calculated. The results showed that, the increased costs due to construction protective measures reach 3.32% of preliminary design approval budgetary estimate, which should be attracted enough attention.
