Abstract. The thick-walled shell of the underwater pipeline experiences a combination of actions of the operational loads (pressure, temperature, weight of concrete coating), taking into account the probability of occurrence of vibration and seismic loads. The strength assessment of thick-walled shell of the pipeline must be done based on the stability check under the combined effect of bending and external pressure. The work objective is to study the special characteristics of the stress-strain state of the underwater pipeline sections with a concrete coating under the seismic loading.

Keywords: thick-walled shell; concrete cover; tangential force; earthquake resistance
