基于三维数值模拟的长大隧洞施工通风影响因素研究

传统通风设计主要依靠经验，不注重影响通风的实际因素，常常给地下工程施工带来不便。构建长大隧洞三维模型，采用基于流体力学理论的三维数值模拟，对比分析隧洞掘进长度、通风方案、断面尺寸、洞壁粗糙高度等因素对通风流场的影响，为优化地下施工通风设计方案提供理论依据。

Based on 3D Numerical Simulation Study Of Factors Affecting Ventilation Long And Large Tunnels Construction

Traditional ventilation design mainly rely on experience, do not pay attention to the actual factors that affect ventilation, Often bring inconvenience to the underground project construction. Build three-dimensional model of long and large tunnels , based on three-dimensional numerical simulation of fluid dynamics theory,comparative analysis of the length of tunnel excavation, ventilation solutions, section size, wall roughness height and other factors on the impact through the romantic field, in order to optimize the design of underground construction ventilation to provide theoretical basis.
