, 1991 A number of structural analysis and CAD system have been developed for structural design, but engineers only apply general purpose structure analysis program to analyze underground structure,which are inconvenient in using. The differences between underground structure and above ground structure are as follows:

Soil Dynamics and Earthquake Engineering, 2019 The seismic response characteristics of underground structures are very different from those of aboveground structures. Great efforts have been made in investigating the influence factors on the seismic responses of rectangular underground structures ...

Underground Archeological Structures Detection
2021This paper introduces and compares three approaches for automatic archaeological heritage site detection hidden under soil cover from public aerial images. The methods use low quality public aerial RGB spectral data restricted by the land-use map to agricultural regions in the vegetation season to detect underground structures influencing plants ...

Seismodynamics of underground structures
Soil Mechanics and Foundation Engineering, 1992Solutions are presented for seismodynamic problems of underground structures which are based on two different approaches: wave dynamics and dynamic theory of earthquake resistance. The results of these investigations are used for solution of problems connected with ensuring the earthquake resistance of structures of the Tashkent subway, constructed in ...

Undrained seismic response of underground structures
2020Underground structures must be able to support static overburden loads, as well as to accommodate additional deformations imposed by seismic motions. It seems well established that the most critical demand to the structure is caused by shear waves traveling perpendicular to the tunnel axis, which cause distortions of the cross section (ovaling for a ...

Loads of Underground Structures
2019The loads on underground structures are complex and the determination method is not perfect enough, which should be studied further. The load action mechanism of underground structures is different from that of the structures on the ground or in the air. Underground structures are buried underground and their loads come from the stratum itself.

Stochastic response of underground structures
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2008This investigation uses a linear elastic finite-element method to analyse the stochastic dynamic response of the Bolu tunnel in Turkey when subjected to spatially varying earthquake ground motion. The research conducts a parametric study to discover the critical magnitude of earthquake ground motion that causes tensile cracking in the reinforced ...
