摘　　要：为达到预期的设计目标,在运营期对桥梁的上部结构控制标高和主桥箱梁的挠度进行有效的观测,监视其变化规律和发展趋势,确保桥梁的安全运营,对桥跨结构线形的监测具有重要意义。通过对蒙新高速公路黑冲沟和牛棚两座连续刚构桥梁采用人工监测其结构线形的论述,为高原峡谷地貌的桥梁监测、管理养护等的研究提供了研究基础依据及范例。To achieve the desired design goals, it is important to observe the control elevation of the bridge upper structure and the main bridge box girder deflection in the operation period, which monitor their changing patterns and trends to ensure the safe operation of the bridge. In this paper, the manual measurement for monitoring two continuous rigid frame bridges named Heichonggou and Niupeng in Meng-Xin Expressway is discussed. The study provides the research base and example for monitoring, agement, conservation of bridges in the plateau canyon landscape.
