摘要
在兰新高铁(新疆段)百里风区十三间房地段,附加线(AF线和PW线)架设施工后,在风力超过5级的情况下,有挡风墙侧的PW线就会发生舞动现象;在风力超过7级的情况下,有挡风墙侧的PW线和AF线均会发生舞动现象。本文针对兰新高铁附加线舞动的情况进行了原因分析,并对附加线舞动处理方案进行了详细阐述,以为类似工程提供借鉴。
After erecting the additional lines( AF line and PW line) along Lanzhou-Xinjiang High-speed Railway( Xinjiang section) in the 13-room section of Baili wind area,there will be waving phenomenon. The PW line with wind-break wall will be shaking when the wind power is more than Grade 5,while the wind power exceeds Grade 7,both the PW line and the AF line will be shaking. This article analyzed the shaking causes of additional line in Lanzhou-Xinjiang High-speed Railway,and described in detail of the shaking processing scheme,in order to provide a reference for similar projects.
