摘　　要：某景观桥改建工程采用一孔75m柔性悬索桥。因桥址地形及道路条件限制,大型施工机械无法进场。采用CPS岩锚体系及小直径钢管桩等创新技术措施克服困难,保证了工程的顺利建成,可供类似桥梁参考借鉴。A landscape bridge reconstruction project is a one-span 75-m flexible suspension bridge. Owning to the restriction of topographic condition at bridge site and road condition, the large-scale construction machine is hard to enter the construction field. The innovation technical measures of CPS rock anchor system and small-diameter steel pipe piles are taken to overcome the difficulties and to ensure the smooth completion of bridge construction, which can be referred for the similar bridges.
