为了保障公路施工现场人员的生命安全,针对安全防护系统建立基于改进云模型的综合评价模型。首先,构建公路施工安全防护系统评价指标体系,从劳动防护用品、人员通道、临边洞口防护和高处作业等4方面开展评价研究;然后,提出一种微调合成算子对权重云矩阵和安全云矩阵进行模糊合成计算,降低熵值对期望的依赖程度;最后,通过正向云发生器生成安全云图和标准云图,评价安全防护系统整体和各级评价指标的安全状态。应用上述方法评价某工程实例。结果表明:该公路施工安全防护系统整体和高处作业的安全等级为良,劳动防护用品的使用和监督安全等级为中;基于改进云模型的安全评价方法具有较好的可行性与适应性,实例评价结果与实际情况基本一致。
In order to guarantee the life safety of the highway construction site personnel, a comprehensive evaluation model based on the improved cloud model is established for the safety protection system. First of all, the evaluation index system of highway construction safety protection system is constructed, and the evaluation research is carried out from four aspects of labor protection products, personnel access, the protection of the edge of the entrance and the working height. Then, aiming at the problem of weighting cloud matrix and safety Cloud matrix to reduce the dependence of entropy on expectations. Finally, the safety cloud and standard cloud images are generated by the forward cloud generator to evaluate the security status of the whole and all levels of evaluation indicators. Application of the above method to evaluate a project example. The results show that the safety grade of the highway construction safety protection system is good and the safety level of the supervision and protection of labor protection products is moderate. The safety evaluation method based on the improved cloud model has good feasibility and adaptability, The evaluation results of the examples are basically the same as the actual situation.
