摘　　要：针对传统火灾多出口疏散场景三维模拟方法存在三维仿真度较低的问题,设计一种古建筑群火灾多出口疏散场景三维模拟方法。获取古建筑群游客特征,包括疏散人数特征、人员构成特征、人员疏散速度特征。其中,疏散人数特征通过对古建筑群进行实地调查获取;人员构成特征通过对游客性别与年龄构成进行调查,获取古建筑群相应人员特征分布趋势;人员疏散速度特征的获取,需要参考人员的形体尺寸与行走速度。通过获取古建筑群游客特征后,根据古建筑群火灾特点,获取古建筑群火灾模型的模型系数,构建古建筑群火灾模型。利用OGRE程序开发工具构建古建筑群火灾多出口疏散三维场景,对古建筑群进行火灾多出口疏散场景三维模拟。实验结果表明,采用上述方法进行三维模拟的效果较好,具有一定实际意义。In this paper, a three-dimensional simulation method for a multi-exit evacuation scene in the fire of ancient buildings was presented. Firstly, the characteristics of tourists in ancient buildings were obtained, including the characteristics of evacuation crowd, personnel composition and personnel evacuation speed. Among these, the characteristics of the number of evacuees were obtained through the field investigation for ancient buildings. The characteristics of personnel composition were obtained through the investigation of the gender and age of tourists. The distribution trend of member characteristics of the ancient buildings was obtained. In order to obtain the characteristics of evacuation speed, it was necessary to refer to the shape, size and walking speed of the people. After obtaining the tourist characteristics in ancient buildings, the fire characteristics of ancient buildings were used to calculate the coefficient of the fire model of ancient buildings, and then the fire model of ancient buildings was constructed. Moreover, OGRE program development tool was used to construct the 3 D scene of multi-exit evacuation, and thus to simulate the three-dimensional scene of multi-exit evacuation in the fire of ancient buildings. Experimental results show that the proposed method has a good effect in 3 D simulation, with practical significance.
