摘要
文章结合宜万铁路堡镇隧道施工实际,介绍了在有轨运输条件下全幅仰拱桥设计与施工的情况。本工程在目前所配备的施工机械设备前提下,解决了仰拱分段一次浇注的难题,可为今后全面推广全幅仰拱施工、根治隧道运营病害提供参考。
The paper introduces the design and application of the invert trestle bridge in Baozhen tunnel on Yiehang - Wangxian railway under the condition of track haulage. Thanks to the trestle bridge the concrete casting of the invert by sections is accomplished by the help of associated equipments. The trestle bridge can be utilized for the invert concreting in similar projects and for the rehabilitation of operating tunnels.
