在架空索道的设计计算中,人们常把确定承载索的中央挠度系数做为主要计算参数,并以此为主要数据对承载索的其他计算项目进行计算和设计。中央挠度系数值在很大程度上左右着承载索的安装张力。承载索的安装张力过大或过小,都将直接影响架空索道的使用效果、钢索寿命和索道运行的安全度。确定适当的中央挠度系数和计算出承载索的安装张力是比较容易的,但要在架设索道的过程中测出钢 In the design and calculation of the cableway, the central deflection coefficient of the carrier cable is often taken as the main calculation parameter, and the other calculation items of the carrier cable are calculated and designed as the main data. The value of the central deflection factor to a large extent about the installation of cable tension. Installation of cable tension is too large or too small, will have a direct impact on the effectiveness of the use of the cableway, cable life and ropeway safety. It is relatively easy to determine the appropriate center deflection factor and to calculate the installation tension of the load cable, but the steel should be measured during the rigging
