Structural-tectonic evaluation of a part of the Branisko tunnel for use of fuzzi logic

Abstract

Branisko tunnel (Slovak Republic) was partly excavated by full-profile drifter. The rock massif deformed by tectonic structures markedly influences energetic and pace demands of tunnel drifter. Analysis of relevant relationships between monitored output data characterizing the process of full-profile excavation and strike of deforming structures by Inversion continual methodology provides a possibility to evaluate physical-mechanical properties of rock massif by interaction of exploitation drifter and rock massif. Statistical structural-tectonic evaluation of deforming systems assigned to deformation stages D1-5 shows directional dependance of spatialy oriented weakness zones of the rock massif and full-profile tunnel drifter.
