| 摘 要： | 山区铁路受复杂的工程地质条件限制,线路工程多以桥隧相接的形式通过大高差的地貌单元,工程中不可避免出现工程构筑物位于高陡边坡。置于高陡峡谷岸坡上的桥梁基础、隧道洞口等工程建筑物与工程边坡相互作用形成特殊的桥隧相连段的工程问题。本文针对不同坡度条件及工程形式分析了桥隧相连部位的工程连接形式及可能出现的工程问题,提出了相应的工程设计建议。

| Abstract: | Because of the complicated geological engineering conditions,mountain railway design often adopts the bridge and tunnel connecting scheme passing through the large difference elevation area,which inevitability encountered the engineering deep slope like bridge foundation and cutting related to the railway construction,and a lot of problems of bridge and tunnel connecting section caused by the interaction between the engineering slope and engineering structure such as bridge foundation and tunnel entrance.This paper discussed the problems of the bridge and tunnel connecting section according to different dip angle and different project forms and put forward the corresponding engineering design proposals. |
