Understanding the resistance coefficient along the tunnel wall is helpful to optimize the ventilation design of tunnel construction and improve the rationality of ventilation scheme. The influence of the height, shape and spacing of rough elements on the resistance coefficient along the tunnel wall is studied. Through the model test and the numerical model, the difference between the empirical formula and the numerical simulation results was explored. The results show that: With the higher height of the rough element on the tunnel wall, the influence on the resistance coefficient along the tunnel wall is less. The shape of rough elements on the tunnel wall has a great influence on the resistance coefficient along the tunnel, and the semi-spherical rough elements have the smallest resistance coefficient along the way. Comparing the calculated results of empirical formula with the numerical simulation results, the difference between them is relatively stable, which is related to the height of rough elements. The correction coefficient α is proposed for the empirical formula, and the corresponding relationship between α and the average roughness height Δ of the wall is α = 1.29+0.024 8Δ.

对隧道壁面沿程阻力系数的认识有助于优化隧道施工通风设计,提高通风方案的合理性。本研究探讨了隧道壁面粗糙单元高度、形状及间距等对沿程阻力系数的具体影响,通过模型试验及数值分析,探究了计算沿程阻力系数的经验公式结果与数值模拟结果的差异。研究结果表明:隧道壁面粗糙单元高度越高,对沿程阻力系数影响趋势逐渐减小;隧道壁面粗糙单元形状对沿程阻力系数影响较大,半球形粗糙单元对应的沿程阻力系数最小;比较沿程阻力系数经验公式计算结果与数值模拟结果,两者的差距较为稳定,与粗糙单元高度有关;对经验公式提出修正系数α,得到α与壁面平均粗糙高度Δ的对应关系为α = 1.29+0.024 8Δ

对隧道壁面沿程阻力系数的认识有助于优化隧道施工通风设计,提高通风方案的合理性。本研究探讨了隧道壁面粗糙单元高度、形状及间距等对沿程阻力系数的具体影响,通过模型试验及数值分析,探究了计算沿程阻力系数的经验公式结果与数值模拟结果的差异。研究结果表明:隧道壁面粗糙单元高度越高,对沿程阻力系数影响趋势逐渐减小;隧道壁面粗糙单元形状对沿程阻力系数影响较大,半球形粗糙单元对应的沿程阻力系数最小;比较沿程阻力系数经验公式计算结果与数值模拟结果,两者的差距较为稳定,与粗糙单元高度有关;对经验公式提出修正系数α,得到α与壁面平均粗糙高度Δ的对应关系为α = 1.29+0.024 8Δ

Understanding the resistance coefficient along the tunnel wall is helpful to optimize the ventilation design of tunnel construction and improve the rationality of ventilation scheme. The influence of the height, shape and spacing of rough elements on the resistance coefficient along the tunnel wall is studied. Through the model test and the numerical model, the difference between the empirical formula and the numerical simulation results was explored. The results show that: With the higher height of the rough element on the tunnel wall, the influence on the resistance coefficient along the tunnel wall is less. The shape of rough elements on the tunnel wall has a great influence on the resistance coefficient along the tunnel, and the semi-spherical rough elements have the smallest resistance coefficient along the way. Comparing the calculated results of empirical formula with the numerical simulation results, the difference between them is relatively stable, which is related to the height of rough elements. The correction coefficient α is proposed for the empirical formula, and the corresponding relationship between α and the average roughness height Δ of the wall is α = 1.29+0.024 8Δ.
