摘要
以某隧道为例,结合隧道施工现状,本着安全、经济、施工可行的原则,经充分分析论证后,确定采用1-25m预应力混凝土T梁与工梁结合的方案,并对隧道衬砌支撑梁施工及运营阶段的结构安全性进行了分析计算。
Taking Dangyangping tunnel as an example,combined with the current construction situation of the tunne,l in accordance with the principles of safety,economy,and feasible construction,after full analysis and demonstration,it is determined that the plan of combining 1-25m prestressed concrete T beam with workbeam is adopted.The structure safety of tunnel lining support beam construction and operation stage is analyzed and calculated.
