基于高分子材料的全风化花岗岩隧道注浆加固技术研究

A polymer material-based study on the grouting reinforcement technology for completely weathered granite tunnels

全风化花岗岩由于其风化程度高,岩体强度低,遇水极易发生崩解,严重危及隧道的施工安全。为了避免全风化花岗岩隧道在施工过程中发生崩解坍塌事故,采用高分子材料进行隧道注浆加固,以保障隧道施工安全。

Completely weathered granite(CWG),for its high weathering degree and low strength of rock mass,would easily disintegrate when exposed to water,which has seriously imperiled the security construction in tunnel.To avoid incidents of CWG disintegration and collapse during the process of tunnel construction,the method of tunnel grouting reinforcement with polymer materials was oftentimes adopted to ensure the safety of tunnel construction.
