Application of Modified LEC Method In the Large Municipal Bridge Construction Hazard Evaluation

As there are more high-altitude, cross, large machinery operations, and with complex process and tight deadlines, plus construction space by the impact of existing traffic of the municipal bridge construction, therefore the construction security risk is high and security management is difficult. In this paper, calculation model and core parameters of classical LEC method are improved and a standard value of each parameter is developed combined with municipal bridge construction safety characteristics. The model applied to the main beam pouring phase hazard evaluation of an elevated bridge achieved good results and show that improved LEC method applied to the municipal bridge construction hazard risk assessment is feasible and scientific.
