【摘要】：随着长大公路隧道的大量修建，斜、竖井在隧道中的作用越来越重要。一方面可以在施工期间增加作业面，加快施工进度，另一方面还可以在运营期间作为通风、逃生通道。但目前涉及斜、竖井综合利用的研究甚少。本文以灵山高速公路建设为依托，在归纳已有斜、竖井功用基础上，采用层次分析法来对斜、竖井的综合效益进行评价研究，并根据灵山高速公路沿线隧道及斜、竖井设置情况，评价了其合理性。在长大公路隧道的运营期间，常常需要采用某种机械方式不断地将新鲜空气送入隧道内。但对于交通量不大或隧道进出口的超静压差或热位差很大的长大隧道，如何将自然通风和机械通风相结合以满足隧道通风的设计要求，研究甚少。本文讨论了自然通风的适用条件，以及设置自然通风井应该注意的制约条件，，结合灵山高速公路的建设，在三个隧道中设置了8个自然通风小竖井，通过现场检测评价了其对运营通风的效果。并以抢风岭公路隧道为重点，研究了利用自然风实现通风节能的措施。
[Abstract]:With the construction of large-length highway tunnel, inclined shaft plays an increasingly important role in the tunnel. On the one hand, it can increase the working surface during construction, accelerate the construction progress, on the other hand, it can be used as ventilation and escape way during operation. However, there are few researches on the comprehensive utilization of inclined and vertical wells. Based on the construction of Lingshan Expressway, on the basis of summing up the functions of inclined shaft and shaft, this paper adopts the Analytic hierarchy process (AHP) to evaluate the comprehensive benefit of inclined shaft and shaft, and according to the tunnel and slope along Lingshan Expressway, The setting of shaft is evaluated and its rationality is evaluated. During the operation of long-road tunnels, it is often necessary to carry fresh air into the tunnel in some mechanical way. However, there is little research on how to combine natural ventilation and mechanical ventilation to meet the design requirements of tunnel ventilation for long tunnels with little traffic volume or great difference of excess static pressure or heat potential between the inlet and outlet of tunnels. This paper discusses the applicable conditions of natural ventilation and the restriction conditions that should be paid attention to in setting up natural ventilation wells. In combination with the construction of Lingshan Expressway, 8 small natural ventilation shafts are set up in three tunnels. The effect of operation ventilation was evaluated by field test. Taking the highway tunnel of Qianfengling as the emphasis, the measures to realize ventilation and energy saving by using natural wind are studied.
