Abstract

In order to prevent accidents in dam construction, the variation of the influence space of the cable crane was analyzed by decomposing the transporting process of the cable crane. According to the size of the roller compacted concrete dam storehouse surface, the number of rolling strips were calculated and the changing characteristics of the working space of the compactor were discussed. The overlapping area between the impact space of the cable crane and the working space of the compactor was analyzed and the spatial conflict strength was calculated. Besides, the implicit time correlation and the frequency of spatial conflict were calculated, and a simulation method of spatial conflict was proposed to comprehensively express the spatial conflict. The results show that this method can provide detailed data for builders before construction, and provide theoretical support to establish reasonable construction scheme and improve construction safety. © 2019 China Safety Science Journal
