Finally, the relationship between vector height and cable force is fitted based on the practical engineering, bedsides, the error is analyzed between design value and measured value, which comes to the conclusion that measured value is good agreement with design value.
Introduction Cableway bridge appeared in the 1960s in China, and has been applied first in terms of military Bridges, turning to civil cableway bridge after mid 1970s, especially in the southwest high canyon in the construction of large hydropower projects ,which are welcomed as a temporary bridge construction.
In this paper, based on engineering rise-span ratio is small, so the parabola method is adopted. 1.1 Equilibrium differential equation Suspension cable shape is determined by the stress, and it is curve under distributed load geometry, as shown in the figure below (Fig.1): Fig.1 Distribution load of cable Fig.2 The force diagram of main cable AB curve expressed by function Take a short cable for free body Then (1) This is the basic equilibrium differential equation of single cable. 1.2 The basic assumptions Cable is ideal for flexible, neither pressure nor by bending.
