结合湖南炎汝高速公路水河特大桥实际情况,探讨了缆索起重机在峡谷桥梁施工中的应用及理论计算,通过精心组织,大胆创新,架设了跨度708 m,吊重10 t的缆索起重机,解决了物资运输难题,确保了施工的顺利开展,也为类似桥梁施工积累了经验。%Combining with the actual conditions of Mishui river Bridge on Yan-Ru highway in Hunan province, the paper explores the application of cable crane in canyon bridge construction and its theoretical calculation. Through careful organization and wise creation, it builds up the cable crane with 708 m in span and 10 tons in hoisting, solves the goods transportation difficulty and ensures smooth construction, and accumulates experiences for similar bridge construction as well.
