【摘要】：以往的隧道疏散時間計算大多基于固定的參數(shù),這樣的假設(shè)條件與實際情況相差較大,計算結(jié)果不能令人滿意。由于隧道環(huán)境多變以及人行為的復(fù)雜性,使得疏散的行為充滿隨機性,文章通過對隧道人員疏散過程的詳細分析,采用隨機方法輸入數(shù)據(jù),利用蒙特卡洛法計算隧道疏散時間,獲得大量隨機計算的統(tǒng)計結(jié)果。統(tǒng)計結(jié)果顯示了疏散行為的隨機性,與一般的仿真模擬方法對比,計算結(jié)果比較接近實際情況。研究結(jié)果表明蒙特卡洛法具有模型簡潔、目標明確、計算快速、參數(shù)易調(diào)整、使用方便等特點,可適應(yīng)隧道疏散復(fù)雜的假設(shè)條件。
[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.
