    摘要
  • 摘要: 隧道施工通风是影响盾构隧道施工效率和安全的重要因素。本文依托苏通GIL综合管廊过江隧道，改进了长距离大直径过江单线隧道，在无竖井和平行导洞、穿越有害气体地层的情况下，在隧道内部结构和隧道掘进同步施工限制条件下的通风技术方案。首先根据相关规范和类似工程的工程经验，选择压入接力式通风方式；然后针对隧道内无轨运输条件、风机风管性能参数等工程现场条件对隧道内的需风量、风机风压等进行了理论计算，充分考虑了局部瓦斯、汽车尾气等有害气体的通风要求；最终对现场的通风方式提出了合理的改进措施，确定了安全有效的通风系统的技术参数，实现了长距离大直径独头5466m压入式通风，为长距离大直径隧道的隧道施工通风提供了参考通风方式。
    Abstract: Tunnel construction ventilation is an important factor affecting the efficiency and safety of shield tunnel construction. The paper proposes a new ventilation system for the large diameter and long distance tunnel construction at Sutong GIL utility tunnel engineering. The tunnel is a single line tunnel without shaft and parallel guide hole, which is crossing gas stratum of Yangtze river bed. Moreover, the tunnel internal structure constructs when the tunnel bores, which causes a huge challenge for ventilation. Firstly, it chose the best ventilation-the forced and relay ventilation, according to the relevant specifications and engineering experience of similar projects. Next, it calculated the required air volume and wind pressure in the restriction of the trackless transport and equipment performance. The effects of harmful gases such as stratigraphic gas and automobile exhaust is fully considered in the calculation. At last, it put forward reasonable improvement measures for the field ventilation and the technical parameters of a safe and effective ventilation system. The measures improved the field construction conditions. The 5466m distance and large diameter tunnel successfully uses the single-head forced ventilation, which is of significance of the similar tunnel ventilation.
