异常黄土地貌下隧道施工安全保障技术

Safety Technology for Tunnel Construction under Abnormal Loess

通过分析几个在异常黄土地层修建隧道时发生塌方的典型案例,总结了几种异常黄土地貌的特点,阐释了产生该种地貌的直接原因,并从地质调查、工程设计、施工过程三个阶段提出了在该种地貌条件下修建隧道时保证施工安全的措施。

This article through the analysis of several construction ofturmels in loess strata abnormal occurs when the typical case of landslides, summarizes the characteristics of several kinds of abnormal loess landform, illustrates the direct reasons for this kind of landscape, and from the geological survey, engineering design, construction process of three stages is put forward in this kind of landscape to build a tunnel under the condition of measures to ensure construction safety
