摘要

为了克服传统安全风险评价方法的主观性,实现地铁施工安全管理的信息化和规范化,基于结构熵权法和可信性测度建立地铁施工安全风险评价模型,然后通过BIM技术制定安全风险控制措施,优化施工方案,并将该模型应用到济南地铁演马庄西站工程实例中.结果表明,运用该模型进行可信性测度综合评价,得出演马庄西站施工过程安全风险水平为Ⅱ级,属于一般风险,其中施工人员的安全意识、机械设备施工安全防护、复合立柱桩施工、安全教育培训执行状况是主要的风险因素,并通过BIM技术重点对风险因素施工工序进行施工模拟和碰撞检测,得出挖掘机和支撑发生碰撞、复合立柱芯柱外包混凝土部分不能与上部顶纵梁形成有效连接等问题,合理优化施工方案,并在对应构件中链接安全信息和注意事项,达到风险控制和信息化施工的目的.该模型评价结果与实际相符,验证了该模型和BIM技术的有效性和可行性.
        In order to overcome the subjectivity of the traditional security risk assessment method and realize the informationization and standardization of subway construction safety management, a subway construction safety risk assessment model was establishedbased on structural entropy weight method and credibility measure, and the safety risk control measures are formulated by BIM to optimize the construction.The model was applied to the Jinan subway Yanmazhuang Station project. The results show that the model is used to conduct comprehensive evaluation of credibility measures, and the performance of Yanmazhuangis obtained. The safety risk level of the construction process of the Yanmazhuang Station is Grade II, which is a general risk includingthe main risk factors ofthe safety awareness of construction workers, the safety protection of mechanical equipment construction and the construction of composite column piles safety education and training implementation status. By using the BIM technical emphases to simulation and test the construction of the risk factors, the problems of the collisionbetween digger and brace and the ineffective connectionof the composite core columnwith the upper top longitudinal beam are found. Then the construction plan is rationally optimized, and the safety information and precautions are linked in the corresponding components to achieve risk control and information construction purposes. The evaluation results of the model are agreed with the actual situation, which verifies the effectiveness and feasibility of the model and the BIM.
