摘要大跨度斜拉橋主梁懸臂拼裝匹配過程中，吊機作用梁段和被起吊梁段由於受力不同，相對變形存在較大差異。 -
It is inevitable that some crane ' s parameter such as working temperature, actual span and so on will change because of the affection of install precision, the change of working condition and actual needs. as a result, it will affect the tension force of carrying cable and carrying capacity. and the tension force and carrying capacity have close relation to the performance of cable crane and operational security
由於纜索起重機工作環境和性質的特殊性，安裝精度的影響、工作環境的變化以及實際工作的需要，不可避免的會引起的各項參數的變化，如工作溫度，實際的跨度等，造成與設計參數之間的差異，從而影響承載索的張力和承載能力，因而直接關繫到起重機的性能和生產的安全性，因此論文研究這些因素變化對張力和承載能力產生的影響，分析張力及承載能力對各因素變化的靈敏度，從而對生產實踐和安全生產作出有意義的指導。 -
