摘要
依据隧道工程中自然风形成的原理出发,从动力和影响因素等方面考虑,分析了自然风压组成的各部分之间内在的联系,得出修正后的自然风计算公式,同时在给出带竖井的条件下,自然风风速计算方法,并通过实际测量和仿真模拟,验证了计算公式有效性,为以后长大隧道自然风的研究提供科学的方法和可靠的依据。
Based on the principle of natural wind forming in tunnel engineering, in view of driving force and affecting factors, this paper analyzed inherent relationship between each component of natural wind pressure, obtained revised formula of natural wind calculation, and a natural wind speed calculation method given a shaft, validated the effectiveness of calculation formula, providing a scientific method and reliable basis for future research in this respect.
