虹梯关隧道位于山西长治至河南安阳高速公路上,隧道全长约2×13.2 km。初步设计阶段对两个通风方案从土建费用、设备费用、运营维护费用、施工难易程度、技术可靠性方面进行了对比分析,确定了左右线均采用斜井分三段纵向通风方案。对于细化通风设计,指出了尚需进一步研究的问题。 Rainbow ladder tunnel located in Changzhi, Shanxi to Henan Anyang Expressway, the tunnel length of about 2 × 13.2 km. The initial design phase of the two ventilation programs from the civil costs, equipment costs, operation and maintenance costs, ease of construction, technical reliability compared to determine the left and right lines are inclined shaft sub-three longitudinal ventilation program. For the refinement of ventilation design, the problems that need to be further studied are pointed out.
