The Failure Mechanism of Concrete Gravity Dams considering Different Nonlinear Models under Strong Earthquakes

Shock and Vibration, 2021
The paper focuses on the failure process and mechanism of the concrete gravity dam considering different nonlinear models under strong earthquakes. By taking a typical monolith of a concrete gravity dam as a case study, a comparative analysis of the ...

Effects of mining subsidence observed by time-lapse seismic reflection profiling [PDF]

, 1995
Extracting coal from underground mineworkings causes the overlying rocks to subside with associated changes in the stress regime. The aim of the study reported here was to apply the surface seismic reflection method to study the effect of subsidence on ...

Post-stack inversion of seismic reflection data from the belvoir coalfield [PDF]

, 1995
Post-Stack inversion of reflection data in seismic exploration can be used to obtain detailed information about lithology variations in the zone of interest. Generalized Linear Inversion (GLI) has previously been applied as a useful tool to achieve this.

High resolution seismic and ground penetrating radar-geophysical profiling of a thermokarst lake in the western Lena Delta, Northern Siberia

, 2002
High resolution seismic and ground-penetrating radar (GPR) have been acquired over Lake Nikolay in the western Lena Delta (Siberia) in order to study the uppermost basin fill and the bordering frozen margins. GPR measurements were completed on the frozen

Slip distributions on active normal faults measured from LiDAR and field mapping of geomorphic offsets: an example from L'Aquila, Italy, and implications for modelling seismic moment release [PDF]

, 2015
Surface slip distributions for an active normal fault in central Italy have been measured using terrestrial laser scanning (TLS), in order to assess the impact of changes in fault orientation and kinematics when modelling subsurface slip distributions ...

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
