发布时间：2018-12-30 18:25
【摘要】：以往的隧道疏散时间计算大多基于固定的参数,这样的假设条件与实际情况相差较大,计算结果不能令人满意。由于隧道环境多变以及人行为的复杂性,使得疏散的行为充满随机性,文章通过对隧道人员疏散过程的详细分析,采用随机方法输入数据,利用蒙特卡洛法计算隧道疏散时间,获得大量随机计算的统计结果。统计结果显示了疏散行为的随机性,与一般的仿真模拟方法对比,计算结果比较接近实际情况。研究结果表明蒙特卡洛法具有模型简洁、目标明确、计算快速、参数易调整、使用方便等特点,可适应隧道疏散复杂的假设条件。
[Abstract]:Most of the previous tunnel evacuation time calculations are based on fixed parameters, which are different from the actual conditions, and the calculation results are not satisfactory. Because of the variety of tunnel environment and the complexity of human behavior, the evacuation behavior is full of randomness. Through the detailed analysis of the evacuation process of tunnel personnel, the random method is used to input the data, and the Monte Carlo method is used to calculate the tunnel evacuation time. The statistical results of a large number of random calculations are obtained. The statistical results show the randomness of the evacuation behavior, and compared with the general simulation methods, the calculated results are close to the actual situation. The results show that the Monte Carlo method has the advantages of simple model, clear target, fast calculation, easy adjustment of parameters and easy to use. It can adapt to the complicated conditions of tunnel evacuation.
