摘　　要：为研究工业区内复杂环境下深基坑支护结构风险状态,利用工作分解结构(WBS)分解工作项目,建立风险指标体系,制订安全预警等级,计算主客观权重并组合赋权,结合三角隶属函数进行多级模糊综合评价,建立深基坑桩锚支护结构风险评价模型。结果表明:模型能很好地反映出深基坑桩锚支护结构所处的风险状态,论证了该模型的可行性与科学性,可为现场管理人员提供借鉴。In order to study risks of deep foundation pit support structures under complex conditions in industrial zones,work items were decomposed based on the work breakdown structure(WBS),a risk index system was developed,safety warning levels were determined,and subjective and objective weights were calculated and combined.The multi-level fuzzy comprehensive evaluation was carried out by the triangular membership function.The risk evaluation model was built for pile-anchor support structures of foundation pits.Results showed as follow the model can well reflect risks of pileanchor support structures in deep foundation pits.It has been proven to be feasible and scientific,thus providing a reference for on-site management personnel.
