摘　　要：公路特长隧道施工的通风是隧道施工中的一大技术难题。根据南方地区雨季较多,全年湿度较大,洞内和洞外温度相差不大,洞内空气流动相对困难的环境条件,从工程施工通风设备的实际出发,通过几种方案的比较,本着“安全、可靠、经济、合理”的原则进行通风方案的优化设计。Ventilation for hiahway super- long tunnel construction is a typical technical problem in tunnel construction. According to ambient conditions for southem area, such as rich rainfall in rainy season, relatively big humidity, small temperature difference inside and outside the tunnel, difficult air flow inside tunnel, this paper suggests optimization design for ventilation in principle of ＂Safety, reliability, economy and rationality＂ via comparison among several solutions based on the practice of ventilation facilities utilized in project construction.
