摘要

摘要本文着重介绍了“Kāty Myscowa”水库设计中的两个压力隧洞。其中一个充当排放管道，而另一个则扮演着充满活力的角色。隧道深度在0米至75米之间，直径等于5米。隧道位于喀尔巴阡山复理石岩体中，该岩体各向异性且不均匀，由砂岩和粘土页岩层组成，并与互层裂缝和众多节理相交。本文分为两部分。第一部分重点介绍隧道的开挖和支护方法，以及隧道的注入和密封（即防水）方法。在第二部分中，使用基于有限差分法的FLAC2D程序对初期支护和永久衬砌的位移和内力进行了数值分析。分析结果可用于评估隧道开挖和开采阶段的条件。

Construction of Pressure Tunnels

Abstract The paper focuses on two pressure tunnels in the design of “Kąty-Myscowa” water reservoir. One of them serves as a discharge conduit, whereas the other plays an energetic role. Their depths range between 0 and 75 metres and their diameters equal 5 m. Tunnels are located in the rock mass of Carpathian flysch which is anisotropic and heterogeneous, composed of layers of sandstone and clay shales and intersected with interbedding fissures and numerous joints. The paper is divided in two parts. The first part focuses on methods of excavating and supporting, as well as injecting and sealing (i.e. waterproofing) the tunnel. In the second part, a numerical analysis using the FLAC2D code based on the finite difference method was carried for calculating displacements and internal forces in the preliminary support and in permanent lining. Results of the analysis allow for the assessment of conditions in the tunnel during its excavation and exploitation stages.
