摘要
基于模糊层次分析法,对川南某山区公路在建项目的深基坑施工进行安全风险评估并作研究,其中一级指标包含5个因素,二级指标包含16个因素。通过邀请相关专家打分,获得评估数值,采用德尔菲法、层次分析法确定指标权重;之后用模糊综合评价法确定项目风险等级。结果表明,本工程基坑施工安全风险评定等级为风险较大,主要风险因素为:现场管理风险>施工作业风险>工程环境风险。
Based on the Fuzzy Analytic Hierarchy Process(FAHP),this paper studied the safety risk assessment of deep foundation pit construction in a mountainous highway project in southern Jiangxi.The first-level index includes five factors and the second-level index includes 16 factors.The evaluation values were scored by the relevant experts.The weights of indicators were determined by Delphi method and analytic hierarchy process.The project risk level was determined by fuzzy comprehensive evaluation method.The results showed that the safety risk rating of foundation pit construction in this project is relatively high.The main risk factors are:site management risk>construction operation risk>engineering environment risk.
