摘要:

 城市小净距隧道在爆破施工过程中,中夹岩柱多次受到扰动,使得其力学行为十分复杂,易发生破坏和失稳。以厦门大学小间距隧道为依托,着重从保护小净距隧道中夹岩柱的原则出发,从爆破施工参数、中夹岩柱加固角度对城市渐变小间距隧道施工技术进行了阐述。

Abstract:

Due to the repeated disturbance to the rock pillars of urban parallel tunnels with small net spacing imposed by blasting construction, the mechanical behavior of the rock pillars is very complex and the rock pillars are subjected to destruction and destabilization. Taking the smallspacing tunnel in Xiameng University as project case, the author, with the aim to protect the rock pillars, expatiates on the construction technology for urban parallel tunnels with changing small spacing in terms of blasting parameters and reinforcement of the rock pillars.
