摘　　要：缆索起重机因其具有跨度大、施工效率高且能够在场地狭窄、岸壁陡峭的高山峡谷中应用的优点已在国内水电项目使用长达50余年。鉴于现有缆索起重机索道系统主索拆除的传统工艺存在拆除工期长、高空作业风险高的弊端,总结并开发出一种缆索起重机索道系统主索拆除施工新技术,彻底解决了主索空中作业的安全风险,省去了架设和拆除临时承载索工序和临时承码安拆工序,有效节约了缆索起重机主索拆除的施工工期,减少了临时承载索和承码保距绳等资源的投入,使得施工效率、经济效益和社会效益显著提高,具有很好的实用价值和推广借鉴意义。The cable crane has the advantages of large span,high construction efficiency,and can be used in narrow sites and steep canyons.It has been used in domestic hydropower projects for more than 50 years.The existing cable crane cableway system of hydropower projects that uses traditional technology has the disadvantages for removing main cables,such as long demolition period and high risk of high-altitude operations.A new technology for the removal of the main cable of the cable crane ropeway system has been summarized and developed,which completely solves the safety risks of aerial operations of main cable,eliminates the process of erecting and dismantling temporary load-bearing cables and the process of installing and removing temporary bearings,effectively saves the construction period for the main cable removal and reduces the investment in resources such as temporary load-bearing cables and bearing distance ropes,and significantly improves the efficiency,economic benefits and social benefits.It has strong practical value and promotion significance.
