Based on the digital twin platform

the intelligent engineering safety analysis and early warn⁃ ing system is studied and designed. The mechanism model of engineering safety monitoring is studied by using the data mining

intelligent analysis and diagnosis technology. To obtain early warning indexes for specific project

the evaluation system and criteria are developed

which has realized intelligent safety analysis and early warning. Moreover

it has been applied to a project and resulted in improvement of the accuracy and timeliness of early warning

enhancement of the level of intelligence

and decisionmaking support for the operation management department.
