The simulation model which can describe the actual evacuation behavior of personnel familiar with the environment in public places accurately was built to guide the development of software with a high degree of simula -tion reliability.The major factors influencing the evacuation behavior of personnel familiar with the environment were analysed and quantified on the basis of referencing Helbing social force model , at the same time , the concept of being climbed degree was introduced to distinguish the influences of different obstacles in the evacuation , and then the model was established combining with the principles of molecular simulation .Finally , the simulation of a representative virtual scene was implemented by using C# programming language .The simulation results showed that the model can fully reflect the evacuation path and move speed change of personnel familiar with the environ -ment , and it is suitable for high-speed rail passenger stations and other public places .%建立能够准确描述熟悉公共场所环境人员真实疏散行为的仿真模型，用于指导编制开发具有较高仿真度的程序软件。该模型是在参考Helbing社会力模型建模思想的基础上，分析和量化影响熟悉环境人员疏散行为的主要因素，同时引入可翻越度概念区分不同属性障碍物对人员疏散行为的不同影响，并结合分子模拟原理建立，最后运用C＃编程语言实现一个比较具有代表性虚拟场景的模拟，其仿真结果显示模型能够较为完整地体现熟悉环境人员的疏散轨迹及移动速度变化，适用于高铁客运站等公共场所。
