摘要

本文描述了喀尔巴阡复理岩体(喀尔巴阡复理岩体)在三条隧道初衬砌钻孔过程中的表现。这些隧道是在“Naprawa”，“Laliki”和“świnna Poręba”挖掘的。这些隧道之间的直线距离为50公里至90公里。详细分析了这些隧道的等值线位移和收敛的结果。将这些值与用于评估隧道环境中岩体行为的指标(zasławski指数和Hoek指数)以及采用的位移和变形极限值进行比较。在此基础上，对已完工隧道初始支护的选择进行了批判性分析，指出了设计阶段的错误。

Assessment of the Behaviour of Flysch Rock Mass During Tunnel Boring in the Primary Lining Using Indicators and Limit Values of Displacements and Deformations

The article describes the behaviour of the flysch rock massif (Carpathian flysch) during the drilling of three tunnels in the preliminary lining. These tunnels were excavated in: “Naprawa”, “Laliki”, and “świnna Poręba”. the distance between these tunnels in a straight line was 50 km to 90 km. the results of the displacement of the contours of these tunnels and their convergence were analysed in detail. These values were compared with the indices used to assess the behaviour of the rock mass in the tunnel environment (zasławski index and Hoek index) and the adopted limit values of displacements and deformations. On this basis, a critical analysis of the selection of initial supports in the completed tunnels was made, showing errors at the design stage.
