隧道高地温应对措施及通风设计——高黎贡山铁路特长隧道可行性研究

Countermeasures against high temperatures in a tunnel and the corresponding ventilation design——Feasibility study for the super-long Gaoligonshan tunnel

文章针对高黎贡山铁路隧道高地温地质情况,通过工程类比并结合理论计算,分析了高地温病害产生的机理及其对工程的不利影响;简要介绍了国内外高地温隧道的工程现状及对隧道高地温病害的应对措施,并着重阐述了高地温隧道的施工通风及运营通风计算方法。可供类似工程参考。

According to the geology of Gaoligongshan tunnel, the mechanism of high geo - temperature and its adverse effect on construction were analyzed by engineering analogy and theoretical computation. The paper also briefly introduces the present situation about the tunnels with high geo - temperatures and the corresponding counter- measures both in China and abroad, and describes in detail the method of computation for the construction and operation ventilation for a tunnel with high geo -temperatures. The study can be taken for reference by similar projects.
