Stability of the Čachtice Underground Corridors

Abstract At the beginning of 16th century, original inhabitants Čachtice built a large complex tunnels and cellars under village, today called underground. The underground protected people from war conflicts, most recently during World War II, as anti-aircraft shelters. Over time, lost its significance. corridors were walled up, covered with rubble, collapsed due to construction work. Later, part was repaired, historical events occurred in such preserved part. Due lawsuit, eventually closed public, it necessary test stability walls A 3D model created, three areas identified which numerical calculations performed Plaxis 2D software. whole is located loess soil. stable if conditions do not change diametrically. calculated factors safety support this assumption.
