Safety check list method inspection project system, complete, can do not missing any key factor can lead to dangerous, to avoid the traditional security checks of the negligence, omission, etc, which can easily be seen in the disadvantages, thus can guarantee the quality of security checks; Can according to the existing rules and regulations, standards, procedures, etc, check, give a good indication of evaluation; Safety inspection table with the method of questions, ask answer, gives the impression of deep, can make people know how to do is right, and therefore can have the effect of safety education; Prepare a list of the safety inspection process itself is a process of system safety analysis, can make the inspection personnel to the understanding of the system is more profound, more easy to find risk factors; To examine the different objects have different checklist, inspection purpose, wide application range.
Fault type and impact analysis is the identification of dedication ideas, rarely overlook important events; Identify risks is completed by the working group together, give full play to the collective wisdom; Arranged beforehand, work carefully. Especially suitable for the system or equipment components may occur at the university of possibility or probability and so on to conduct a comprehensive and systematic qualitative and quantitative analysis, and in view of the fault condition is put forward corresponding detection methods and preventive measures, and thus has strong systematic, comprehensive and scientific.
Expert appraisal method also calls the qualitative evaluation method and comprehensive evaluation method, the bid evaluation committee according to the predetermined evaluation content, such as quotation, time limit for a project, technology scheme and quality, etc., for each item of bidding documents together with qualitative analysis, comparison, after review, select the bid documents in all the indicators are a good candidate for the winning bidder, you can also use a vote of the way to determine the candidate for the winning bidder. This approach is, in fact, qualitative method.
Through the use of these safety assessment methods for hazard identification, can the construction safety management in the process of feasible suggestion put forward all kinds of safety measures.
Key words: large span Bridges; Hazards identification; LEC method; The accident tree method; Safety construction organization design.
Keywords: large-span bridges; development; bridge major security incidents; reduced; reasonable
