工程地质的剖析在云桂铁路隧道群施工中的指导及应用

摘要

隧道工程地质构造形态多样、岩性变化频繁.如果忽视工程地质的作用,对岩土性质特点认识不足,势必会造成不必要的经济损失,给施工安全质量带来危害.文章以云桂铁路隧道群施工为例,探讨了不同地质条件下的岩性特点.通过对工程地质的剖析,综合分析岩性特点,准确判定围岩特性,从而制定相应的施工措施,才能科学合理地指导施工,确保施工进度.%Insufficient understanding of the characteristics of surrounding rock may cause problems with construc-tion quality and economic losses due to various types of geological structures and the frequent change of rock mass properties during tunnel construction. Based on the construction of tunnels on the Kunming-Nanning passenger ded-icated line, this paper discusses the characteristics of surrounding rock under different geological conditions and proposes corresponding measures in light of a comprehensive engineering geological analysis in order to give scien-tific guidance and ensure construction progress.
