Abstract
In order to strengthen the construction risk management of underground engineering projects, reduce the probability of accidents, and ensure that the underground engineering completes the construction tasks on schedule, the article relies on a certain subway engineering project to carry out research from the aspects of risk identification, risk factor analysis, and risk factor evaluation. The article adopts analytic hierarchy process and fuzzy comprehensive evaluation method to carry out risk factor evaluation weight analysis and risk system evaluation in the construction process, and then realize reasonable prediction and evaluation of construction risk factors. Finally, this essay sorts out the prevention and control measures of underground engineering construction risk management from five aspects of personnel, machinery, management, environment and technology, and then provides auxiliary decision-making for underground engineering construction risk management.
Highlights
The development and utilization of underground space are an important way to solve urban problems and improve people’s living environment[1]
Underground engineering can well solve a series of problems brought about by rapid economic development and insufficient urban available space[2]
Most underground engineering accidents occur in the construction phase, and risk management during the construction phase has always been the focus of research in the field of underground engineering
Summary
The development and utilization of underground space are an important way to solve urban problems and improve people’s living environment[1]. Tang Yuchun[4] believes that there are mainly construction personnel risks, shield construction safety risks, construction environment safety risks, and organization management safety risks during the construction phase; Qian Qihu[3] believes that the underground engineering construction process mainly faces safety management hazards, water, and mud inrush geological disasters, and rock burst geological disasters. It can be seen from the above research states that there are many risk factors in the process of underground engineering construction, involving multiple dimensions. Rank the importance of risk factors, and establish a safe production index system, hoping to provide help for the risk management of underground engineering construction
