高速公路桥隧连接工程中隧道洞门施工技术

On construction technique of tunnel portals based on bridge and tunnel connection projects on highways

对高速公路桥隧连接工程的隧道洞门施工技术进行了探究,分别从隧道洞口的选址、隧道洞口浅埋段、偏压段及岩堆段的施工关键技术等方面作了具体阐述,对提高高速公路桥隧连接工程质量具有重要意义。

The paper researches the tunnel portal construction technique in the bridge and tunnel connection projects on highways,and has the factual illustration the key construction techniques from the address selection for the tunnel portal,the shallow buried section of the tunnel portal,the side-pressure section and the rock heap one,so it is meaningful for improving the quality of the bridge and tunnel connection projects on highways.
