Safety Risk Coupling of Construction of Super-High Pier Column Based on N-K Model

Based on the analysis of the safety risk factors in the construction of super-high piers and columns, four categories of influence factors, including human factors, material factors, environmental factors, and management factors, were summarized. Based on the N-K model and combined with the actual engineering cases, the probability of single factor risk coupling, double factors risk coupling, multi-factors risk coupling, and the corresponding coupling value of each coupling mode were calculated. Furthermore, the influence degree of each coupling mode on the construction safety of super-high piers and columns was explored, and the reasonable suggestions were put forward to reduce or avoid the probability of safety risk accidents in the construction of super-high piers and columns.
