摘要:

为了对高地应力区的隧道设计、施工阶段的围岩分级进行客观评价,提高判定数据的可靠性,以兰渝线高地应力软岩隧道大变形的围岩特征为基础,结合国内其他软岩变形隧道,通过总结以地质因素为主的变形受控条件,探讨软岩变形机制,对高地应力区软岩进行软Ⅰ级~高软Ⅳ级分级,以期为以后的隧道结构设计提供科学准确的依据。

Abstract:

Deformation (mainly caused by geology conditions) control factors are summarized, deformation mechanism of soft rock is discussed, and soft rocks in high ground stress zones are classified, with the large deformation characteristics of soft rock tunnel in high ground stress zones on LanzhouChongqing railway as an example, so as to objectively estimate the design and surrounding rock classification of tunnels in high ground stress geology conditions.

Key words: soft rock tunnel, LanzhouChongqing railway, high ground stress, deformation control factor, deformation mechanism, soft rock classification
