装配式建筑吊装安全风险管理数字孪生模型建立方法

装配式建筑因其施工方便、绿色环保等优点被大力推广。吊装作业作为装配式建筑施工过程的关键环节，其涉及的安全管理要素多且关系复杂。目前的吊装安全风险管理方法仍存在智能化水平低、预测精确度无法保证、安全管理要素无法实时控制等问题。针对以上吊装安全风险管理问题，本文将数字孪生概念引入吊装安全风险管理领域，分析了吊装安全风险诱发因素，搭建了面向吊装安全管理的数字孪生框架，阐述了数字孪生模型的运行机制。同时，针对数字孪生建模这一关键问题，提出物理吊装过程、虚拟吊装过程、虚实信息交互的建模方法，并在某项目中进行实际应用，验证了方法的有效性，为数字孪生在吊装安全风险管理方面的应用提供了理论支撑与技术支持。

Establishment Method of Digital Twin Model for Hoisting Safety Risk Management of Assembly Building

Assembly building has been vigorously promoted due to its convenient construction and green environmental protection. As a key link in the construction process of prefabricated construction, hoisting operation involves many safety management elements and complex relationships. The current hoisting safety risk management methods still have problems such as low intelligence level, unguaranteed prediction accuracy, and unreal-time control of safety management factors. In view of the above hoisting safety risk management problems, this paper introduces the concept of digital twin into the field of hoisting safety risk management, analyzes the inducing factors of hoisting safety risk, builds a digital twin framework for hoisting safety management, and expounds the operation mechanism of digital twin model. And based on the key problem of digital twin modeling, the modeling methods of physical hoisting process, virtual hoisting process and virtual and real information interaction are proposed, which have been put into practice in a project to verify the effectiveness of the method, providing theoretical support and technical support for the application of digital twin in hoisting safety risk management.
