Abstract. The paper presents deformations
of tunnel structures under the influence of earthquakes. The seismic impact
on shallow laid tunnels in saturated soil of low bearing capacity was considered
through the analysis of longitudinal and transversal loads. Stress and
strain states were specially analyzed.
Key words: shallow-laid tunnels,
seismic load, stress state, structural deformation
STANJE NAPONA I DEFORMACIJA USLED
UTICAJA ZEMLJOTRESA NA
PLITKO POLOŽENE TUNELSKE OBJEKTE U ZASIĆENOM SLABONOSIVOM TLU
U radu se prikazuju deformacije tunelskih konstrukcija
usled delovanja zemljotresa. Predmet razmatranja bili su seizmički uticaji
na plitko položene tunele u zasićenom tlu slabih karakteristika kroz
analizu podužnih i transverzalnih opterećenja. Posebno je analizirano
naponsko i deformacijsko stanje.
