| 摘 要： | 深基坑工程施工中安全事故的发生给社会及施工企业带来了不良影响和巨大的经济损失,如何减少深基坑工程安全事故发生率,降低工程风险是一个值得研究的问题。本文通过将模糊理论与故障树分析方法相结合,建立了基于模糊故障树法的深基坑支护工程项目风险评估模型,克服了传统故障树方法忽略底事件发生概率的不确定性这一缺陷。通过对某深基坑工程实例的计算分析,说明了本文所建立的模型在深基坑工程风险评估中具有较好的理论价值与实际应用价值。

| Abstract: | Deep foundation pit engineering construction safety accident to the society and the construction enterprise to bring the bad influence and huge economic losses. How to reduce the incidence of deep foundation pit engineering accidents, reduce the project risk is an issue that is worth studyingat. This paper established deep foundation pit supporting project risk assessment model based on fuzzy fault tree method through combining the fuzzy theory and the method of fault tree analysis. It overcome the defect of traditional fault tree method that ignore bottom event of the occurrence probability of the uncertainty. Based on the calculation and analysis of a deep foundation pit engineering example, this paper illustrates the model in deep foundation pit project risk evaluation has good theoretical value and practical value. |
