Study on the Effect of Structural Parameters for Safety Performance of Cable Barrier

並列摘要


With the numerical modeling method, the effect of three parameters, which are the spacing of the stand column, the initial tension and the installation length in the structure of the cable barrier, on its safety performance was analyzed in this paper. Research suggests the effect of the spacing of the stand column on the cable barrier is significant. When the initial installation tension and the installation length are determined, and its spacing of the stand column is 6 m, the safety performance of the barrier structure is relatively superior. In the case that the clear width of the roadside meets the requirement, it is reasonable that the initial tension of the cable barrier is between 30 kN and 35 kN. For the installation length, above a certain installation length, the effect of its change is relatively small. Analytical results can be referred by the design.
