Based on the basic theory of factor analysis, this paper analyzes the risk factors of large-scale bridge construction through questionnaire surveys and expert scoring methods, summarizes the basic data of factors affecting bridge construction, and then analyzes the possible application of factor analysis in bridge construction risk analysis Sex. Based on the statistical processing of the data by the IBM SPSS Statistics V21.0 software, the applicability of the method was verified through factor extraction, factor rotation, consistency analysis and construction validity, and pointed out that six types of main factors affecting the safety of bridge construction Factors, calculate the importance index and correlation of each risk factor, and sort them by size, so as to estimate the risk consequences of bridge construction in a targeted manner, and invest reasonable efforts to control according to the size and importance of the risk, so that the risk control process is more Reasonable and targeted.
