仙人峒超特长隧道竖、斜井设置方案研究及探讨

Study on the Shaft and Inclined Shaft Scheme for the Extra-large Xianrendong Tunnel

长度超过7 km的高速公路特长隧道往往需要设置竖、斜井来满足通风需求。通过对国内已建成长度大于7 km的公路隧道通风方式进行调研,发现其竖、斜井的设置存在一些问题和不足。基于此,文章以韶关市某高速公路仙人峒隧道为工程实例,提出了特长公路隧道通风竖、斜井设计的基本思路和方法,可对今后类似隧道工程设计起到借鉴作用。

It is necessary to set shaft and inclined shaft for the highway tunnels being longer than 7 km to meet ventilation requirements.In light of a research on the ventilation methods for the existing highway tunnels more than 7 km long,it is found that there are some problems for the setting of shaft and inclined shaft.Taking the Xianrendong tunnel for example,the basic ideas and method for the design of shaft and inclined shaft of the extra-long highway tunnel are proposed.
