Study On Safety Risk Of Pipeline Crossing Highway Construction

During the 14th five-year plan period,China has entered a new stage of development.With the coordinated advancement of new-type infrastructure construction and the orderly development of the national comprehensive three-dimensional transportation network,the density of underground pipelines and the coverage area of highways will be greatly increased,new Pipelines are also much more likely to cross existing roads.In recent years,pipeline construction safety accidents occur frequently,and the safety risk management of pipeline under-crossing highway construction is widely concerned,so it is necessary to study the safety risk management of pipeline under-crossing highway construction.In this paper,the method of fuzzy comprehensive evaluation and analytic hierarchy process is used to evaluate the risk of the construction process of pipeline under the highway,the fuzzy comprehensive evaluation is used to construct the fuzzy evaluation matrix of the risk evaluation index in the criterion layer,and the analytic hierarchy process is used to quantitatively reflect the influence of each risk factor in each construction risk evaluation index on the construction safety,the fuzzy evaluation matrix is combined with the weight of the risk evaluation index,and the Comprehensive Evaluation set of the risk index is obtained,and the concrete evaluation result is obtained according to the principle of maximum membership degree,and then put forward the corresponding countermeasures and suggestions.In this paper,the domestic and foreign research status of pipeline underpass highway and construction risk assessment is analyzed,and the necessity of safety risk management of pipeline underpass highway construction is described Secondly,it describes the pipeline underpass,risk assessment,risk assessment methods,and then introduces the construction process of the pipeline underpass highway construction risk assessment system,considering the characteristics of the project comprehensively,the risk grade of the project is calculated by using the method of comprehensive fuzzy evaluation and the method of tomographic analysis,and the corresponding safety risk countermeasures and suggestions are put forward according to the evaluation results,it provides reference for the safety risk assessment of the same type of construction project...
