渠道毗邻既有铁路线路爆破开挖技术

Analysis of the Blasting Excavation Technology of the Channel Adjoin to the Existing Railway Circuit

渠道毗邻既有铁路公路隧道施工,往往是地理条件恶劣、施工难度比较大的位置。如何制定行之有效的爆破开挖技术,是目前亟需解决的一个课题。因此,本文笔者根据海南大广坝二期干渠工程,对爆破开挖技术进行了阐述。

The railway and highway tunnel construction adjo-in to the channel always has poor geographical conditions and difficult construction place. How to develop the effective exca-vation blasting technology is a topic which needs to be set led. Therefore, in this article, the author bases on the second phase of large dam in Hainan and elaborate the blasting excavation t-echnology.
