In order to scientifically manage and control tunnel and underground engineering construction risks, a set of tunnel and underground engineering risk management software was developed using the established engineering risk analysis theory and method. The software can automatically generate an engineering risk survey form based on the proposed project information and data, combined with a large amount of tunnel and underground project risk data stored in the risk alternative database, and carry out risk identification, estimation and evaluation of the proposed project to achieve scientific risk decision-making and management. At the same time, the software can conduct real-time analysis and evaluation based on the construction progress of the project, and use construction monitoring data to dynamically track and manage various risks in the project under construction, comprehensively control the risks during construction, and ensure the smooth progress of the project. The basic functions of the software include: engineering risk data storage, auxiliary risk identification, risk estimation calculation and risk evaluation, risk decision-making and risk tracking management, etc.<o></o>
