Research on Safety Assessment of Blasting Construction in Highway Tunnel Project

Abstract:

The drilling and blasting method is popular for the construction of highway tunnel,which is easy to cause serious production safety accidents.Based on safety risk analysis of tunnel blasting construction,safety risk probability assessment index system of tunnel blasting construction was put forward,which consist of establishment of blasting scheme,belection of blasting equipment,and safety management,etc.Safety risk probability assessment model was constructed based on the fuzzy comprehensive evaluation,which are divided in five level.The risk matrix method was used to assess risk level of blasting construction,considering blasting construction risk probability and the consequence.Through the case on ChenJiagou tunnel in the province of Hebei proves the feasibility of evaluation method,and the corresponding risk control measurements were proposed.
