塔式起重机拆卸是建筑行业中最危险的作业之一。塔式起重机的安装和拆卸占所有起重机事故死亡人数的10-12%。由于这项工作的性质，离岗培训是不可行的，所需的知识和专门技能必须在工作中获得。然而，虚拟训练器，如微软飞行模拟器为飞机飞行员和任务彩排演习（MRE）为军队人员已经开发出来，并且已知提供了一个非常成功的手段，克服这种在职学习所涉及的风险，显然在建设情况下具有潜力。本文介绍了新开发的多用户虚拟安全培训系统（MVSTS），旨在为参与塔机拆卸的人员提供类似的学习环境。所提出的训练系统是通过修改现有的游戏引擎来开发的。在接近现实的虚拟环境中，学员可以参与虚拟拆解过程。在此过程中，他们学习了正确的拆卸程序和工作地点，并通过虚拟拆卸起重机与其他学员合作。该系统允许学员在无风险的环境中体验整个过程。通过案例分析，说明了该系统的工作原理及其实际应用。该系统通过与30名不同背景的建筑专家的访谈进行评估，根据他们的经验分为三组，分别通过传统和虚拟方法进行培训。结果表明，该系统的受训者总体上优于传统方法的受训者。评级还表明，该系统总体上具有作为培训平台的巨大潜力。DOI: 10.1061 /(陈纯)cp.1943 - 5487.0000170。(C) 2012美国土木工程师学会。
Tower crane dismantling is one of the most dangerous activities in the construction industry. Tower crane erection and dismantlement causes 10-12% of the fatalities of all crane accidents. The nature of the task is such that off-the-job training is not practicable, and the knowledge and expertise needed has to be gained on the job. However, virtual trainers such as Microsoft Flight Simulator for airplane pilots and mission rehearsal exercise (MRE) for army personnel have been developed and are known to provide a highly successful means of overcoming the risks involved in such on-the-job learning and clearly have potential in construction situations. This paper describes the newly developed multiuser virtual safety training system (MVSTS) aimed at providing a similar learning environment for those involved in tower crane dismantlement. The proposed training system is developed by modifying an existing game engine. Within the close-to-reality virtual environment, trainees can participate in a virtual dismantling process. During the process, they learn the correct dismantling procedure and working location and to cooperate with other trainees by virtually dismantling the crane. The system allows the trainees to experience the complete procedure in a risk-free environment. A case study is provided to demonstrate how the system works and its practical application. The proposed system was evaluated by interviews with 30 construction experts with different backgrounds, divided into three groups according to their experience and trained by the traditional and virtual methods, respectively. The results indicate that the trainees of the proposed system generally learned better than those using the traditional method. The ratings also indicate that the system generally has great potential as a training platform. DOI: 10.1061/(ASCE)CP.1943-5487.0000170. (C) 2012 American Society of Civil Engineers.
