摘要 针对深基坑工程施工过程中潜在风险因素众多而难以识别的问题,提出基于直觉模糊优劣解距离法(TOPSIS)的多属性评价方法对风险因素进行评估。首先,基于基坑安全事故案例、专家工程经验和实际工程,分析并确定潜在的风险因素;进而,根据风险因素构建风险评价体系,应用直觉模糊数确定专家和评价准则的权重;最后,运用TOPSIS多属性决策方法识别和评估潜在的风险因素。最终通过实例验证了该方法的可行性。研究表明:本方法可有效识别施工过程的高风险因素,可作为基坑施工安全风险分析与控制的决策工具。 The complexity of deep-excavation construction arises from the influence of various potential risk factors on the construction procedure.To address this issue,this study introduces an intuitionistic fuzzy TOPSIS method aimed at identifying potential high-risk factors.Initially,potential risk factors were determined through an analysis of the failure modes derived from prior excavation accidents,insights from practical engineering projects,and the expertise of engineering professionals.Subsequently,a risk evaluation hierarchy was established,and weights were assigned to experts and criteria using intuitionistic fuzzy numbers.A practical project involving a deep excavation was conducted to validate the feasibility of the proposed method.The results indicate that the TOPSIS method effectively identified high-risk factors.The developed method serves as a valuable decision-making tool for the safety risk analysis and control of excavation construction in similar engineering projects.
