Influence of earthquakes on the stress and strain state of the shallow tunnel structures in saturated soil of low bearing capacity

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.U radu se prikazuju deformacije tunelskih konstrukcija usled delovanja zemljotresa. Predmet razmatranja bili su seizmicki uticaji na plitko polozene tunele u zasicenom tlu slabih karakteristika kroz analizu poduznih i transverzalnih opterecenja. Posebno je analizirano naponsko i deformacijsko stanje.
