摘要
为了研究深大基坑支护项目施工时危险源的评价体系,根据危险源差异性,将其分为结构性失效危险源(J)和非结构性失效危险源(N),运用层次分析法对危险源进行了研究,建立了一套基坑支护项目危险源评价模型,并应用于实际工程中。研究结果表明:采用层次分析法建立的模型A=0.67J+0.33N,可以在评价过程中充分考虑危险源种类,评价结果符合工程实际情况,模型可靠准确并且具有针对性。研究成果可为类似项目的危险源评价提供借鉴与参考。
In order to study the evaluation system of hazard sources during the construction of deep and large foundation pit support projects,this paper divides them into structural failure hazard sources(J)and non-structural failure hazard sources(N)according to the difference of hazard sources.The hazard source is studied by the analytical method,a set of hazard source evaluation model for foundation pit support project is established,and it is compared with the actual project.The research results show that the model A=0.67 J+0.33 N established by the analytic hierarchy process can fully consider the types of hazard sources in the evaluation process,the evaluation results are in line with the actual situation of the project,the model is reliable,accurate,and targeted,the research results can provide reference and reference for the hazard evaluation of similar projects.
