地下工程软岩支护施工技术分析

Discussion on the Construction Technology Progress of Soft Rock Support in Underground Engineering

中国地质条件复杂多样,地下工程开挖后,围岩应力状态通常会发生很大变化,从而造成重大安全事故,尤其是在面临软弱围岩的情况下,会进一步阻碍地下建设工作的进行。我国目前尚未形成完整的一套体系来解决这类技术难题。基于此,文章通过研究国内外已有文献资料具体论述软岩支护的技术分析,旨在为地下工程软弱围岩支护建设提供技术理论支持与参考。

China's geological conditions are complex and diverse.After the excavation of underground engineering,the stress state of surrounding rock usually changes greatly,causing major safety accidents,especially in the face of weak surrounding rock,which will seriously hinder the underground construction work.At present,there is not a complete set of system to solve such technical problems in China.This paper discusses the technical analysis of soft rock support by studying the existing literature at home and abroad,hoping to provide a simple technical theoretical support and reference for the construction of soft rock support in underground engineering.
