This article explores the construction safety risk of the shallow-buried undercutting method for urban underground comprehensive pipe galleries,and analyzes the construction safety risk factors of the shallow-buried undercutting method for underground comprehensive pipe galleries,identifying and determining the disaster risk factors of the construction safety of the shallow-buried undercutting method.Based on this,this paper constructs an index system of the construction safety risk of the shallow-buried undercutting method for urban underground comprehensive pipe galleries,which includes the five aspects of technical risk factors,personnel risk factors,environ-mental risk factors,material and machinery risk factors and construction management risk factors,introduces a Bayesian network model for the construction safety risk assessment of the shallow-buried undercutting method,and proposes the key issues of the construction safety risk of the shallow-buried undercutting method for urban under-ground comprehensive pipe galleries.
