Based on engineering practice this paper points out that dangerous engineering is the key and difficult point of engineering management.This papaer raises issues with the hazardous engineering control，such as identification of major hazardous engineering,poor quality of special plan preparation,formal disclosure of special plans,prominent issues in the implementation process,not thorough enough in the acceptance process,partial failure of work program.This papaer roposes the key points for such as identification of major hazardous engineering,plan preparation,plan disclosure,field Control,work procedure.This papaer delves deeply into all these matters.
