Geotechnical structures buried near the ground surface have a wide range of applications, from small-scale pipelines
such as means of gas transmission, telecommunications, water supply, and sewerage pipelines, to large-scale structures
including tunnels for various transportation systems. This paper provides an overview of the current understanding of the
failure mechanisms of these structures due to earthquake loadings. Based on post-earthquake investigations,
experimental laboratory data as well as numerical simulations of underground structures conducted in the current study
by means of computer code, FLAC, it was found that movement of ground at seismic load may cause serious damage to
those infrastructures. These serious damage is represented in two main types of failure has been occurred. First, stressstrain
failure of the underground structure due to extra-stress and extra-deformation which as a result of soil movement
at seismic. Second, state the stress failure of soil which lead to an uplift of underground structures and collapse of
surround soil then disconnection of pipe joints between buried structure and tubes.
