| Abstrait: |
The risk assessment has been studied for bridge Construction, in order to reduce the occurrence probability of the accident and ensure the personnel and structural safety. The hierarchical decomposes method has been used in the project to decompose the construction phase of each part and to identify the basic risk sources; by the way of letter inquiry to consult experts for analysing and estimating the risk; according to risk probability and risk level assignment to determine risk value; the risk list has been ultimately formed. We must consider the acceptable level of risk; the decision-makers can make optimal decisions using the theoretical achievement. The risk assessment used in the continuous prestressed concrete beam bridge construction phase has given good results and gained high appraisal. |
