高海拔隧道施工氧含量安全控制标准研究

Study on Safety Control Standard for Oxygen Content in the Construction of High-Altitude Tunnel

高海拔隧道施工过程中的缺氧问题直接制约着着隧道建设。文章通过研究人体的缺氧规律,总结了隧道施工环境缺氧分级评价方法,得到了适用于隧道施工的含氧量标准的计算公式,并通过高海拔隧道施工现场测试,进一步验证了高海拔隧道施工缺氧评价方法及氧含量控制标准理论的可行性及正确性。

The problem of hypoxia in the construction of high-altitude tunnels directly restricts the tunnel construction.Through studying the hypoxia rule of human body,this article summarized the hy- poxia grading evaluation method of tunnel construction environment, obtained the calculation formula suitable for the oxygen content standard of tunnel construction, and through the construction field test of high altitude tunnel, it further verified the hypoxia evaluation method for high-altitude tunnel con- struction as well as the feasibility and correctness of oxygen content control standard theory.
