ABSTRACT

The fuzzy analytic hierarchy process and set pair analysis theory are introduced to establish a comprehensive safety risk assessment method to scientifically carry out the safety risk assessment of foundation pit engineering construction process. Based on the monitoring data of the actual project, a comprehensive safety risk assessment of a foundation pit engineering construction process is carried out. This method can effectively reflect the evolution process of safety risk in the construction process of a foundation pit and determine the risk source in combination with construction records and monitoring data, providing significance guidance for engineering construction. It also verifies the rationality and practicability of the engineering application of the comprehensive risk assessment method and provides a useful reference for risk assessment of similar deep foundation pit construction.
