Research On The Highway Overpass Construction Safety Risk Identification And Evaluation

Large-scale Foundation Engineeringplay a significant social and economic benefits,while increasing the risk of problems faced by the government and the public’s attention.Itoften needs to face many risks what are difficult to predict due to it’s large-scale, complexconstruction characteristics. Construction of the highway overpass such as large constructionprojects inevitably serious accidents occur frequently, so for its construction process of riskidentification and assessment is particularly important.Highway overpass in the constructionprocess due to the diversity and the need for construction at the same time in different areas atthe same time the source and risk management issues such as the construction of content,making it more difficult during the construction phase of risk management.Managers shouldbe struggling for such construction management.Paper combines the characteristics of highway overpass construction risk fromenvironmental factors, human factors, technical factors bridge construction, equipmentmanagement factors, material factors to analyze these aspects overpass construction risk.Forall aspects of bridge construction phase may exist accidents risk identification study analyzesthe characteristics of overpass construction risk, describes the overpass construction processcommon risk types.Summarizes the risk identification process of bridge construction phase,the basis and method by analogy, analyze, summarize, draw bridge construction risk factorsmay arise. Then overpass construction methods and procedures for risk assessment areintroduced. Meanwhile analyzes several risk assessment methods currently exist. This articleuses AHP Xing Heng highway overpass construction in jujube orchards exchange project riskassessment to determine the risk of the construction phase of the event and the level of riskweights, and because often the right to remain constant and often does not reflect theshort-board effect resulted in findings unscientific question its right to deal with variableweights, finally get a reasonable heavy weight of each risk event, highlighting the major riskevents.Papers in the process of risk analysis as the main line, through the use of AHP overpassconstruction process of risk analysis, providing the basis for the risk management. On thebasis of risk assessment models and procedures, we give a large-scale inter-provincial,national highway bridges cross the evaluation criteria for the construction phase of the riskassessment and acceptance criteria. According to the probability of the risk may occur, theconstruction of the qualitative and quantitative risk estimates. Approach to risk identificationand assessment of overpass construction will be applied to the actual establishment of the project, and the evaluation results and the actual bridge construction risk events werecompared, the final preliminary results of use in the construction process of such riskassessment system.
