SRT-Ai: Identifying seismic reflection terminations using deep learning

Applied Computing and Geosciences
Seismic stratigraphy entails a regional scanning (reconnaissance) of seismic data to identify and annotate seismic reflection terminations. To identify these terminations in modern 3D seismic datasets, interpreters have to examine thousands of inlines ...

Cost Estimation of Structural Components of a Building by considering the Seismic Load on Different Regions

Advances in Civil Engineering, 2019
Seismic loads should be considered in the cost estimation process as a consequence of changes in structural dimensions. Seismic loads received by buildings vary from one region to another, which are used as a basis for dimensioning structural components.

Quantitative assessment of the spatio-temporal correlations of seismic events induced by longwall coal mining

Journal of Rock Mechanics and Geotechnical Engineering, 2022
Rock failure process as a natural response to mining activities is associated with seismic events, which can pose a potential hazard to mine operators, equipment and infrastructures. Mining-induced seismicity has been found to be internally correlated in

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Form and load transfer aspects of foundation systems: Case‐based implementation and adaptation for buildings

Deep Underground Science and Engineering, EarlyView.
Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...

Wave theoretic seismic processing. [PDF]

The Journal of the Acoustical Society of America, 1991
The goal of seismic processing is to determine the character of the subsurface of the earth from wave-field measurements on the surface. In this inversion problem, both the target and the propagating medium are unknown. Also, the character of the energy source is not typically known. In this paper, the evolution of methods which address various aspects

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

Deep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...
