Study on Construction Safety Risk Classification Methods of Bridge Engineering

Abstract

With the progress of productivity, various accidents occur frequently, especially in the engineering construction process. Bridge construction has the characteristics of long construction period and heavy workload, and many factors make it impossible to accurately determine the risk level of the construction activity. At present, there are many risk classification methods widely used in the engineering construction field. It is very important to select an appropriate method to determine the risk level. Therefore, it is necessary to conduct a comparative study of risk classification methods. Based on the analysis of the major risks on the construction process, this study simultaneously used the work condition risk appraisal method(LEC) and LC method to evaluate specific engineering. The results show that LEC method is more suitable for estimation of risk level than LC method in the engineering construction field. Accurate estimation of risk level not only is helpful for the construction unit to make scientific and reasonable risk control measures and construction schemes, but also can effectively reduce the frequency of accidents and property losses.
