Improving the Performance of Seismic Wave Simulations with Dynamic Load Balancing

open access: yes2014 22nd Euromicro International Conference on Parallel, Distributed, and Network-Based Processing, 2014
Seismic wave models provide a way to study the consequences of future earthquakes. When modeling a restricted region, these models require a boundary condition to absorb the energy that goes out of the simulated domain.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Dynamic response of offshore wind turbine monopile foundations in layered soils under wind, wave and earthquake actions

open access: yesApplied Ocean Research
Earthquakes occur frequently in China’s southeast coastal areas. Therefore, in this region, offshore wind turbine (OWT) structures are highly likely to be simultaneously affected by wind, waves and earthquakes. Firstly, based on the wave theory and Snell’

Dynamic Response Analysis of Buried Drainage Pipes for Polymer Grouting Trenchless Rehabilitation under the Traveling Wave Effect

open access: yesAdvances in Civil Engineering, 2022
The polymer grouting nonexcavation repair technology has been widely used in the repair of underground pipeline leaks, but the seismic response to the polymer repair pipeline is currently using a consistent excitation of seismic input without considering

Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

open access: yesDeep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.

A multiphase seismic investigation of the shallow subduction zone, southern North Island, New Zealand [PDF]

open access: yes, 2001
The shallow structure of the Hikurangi margin, in particular the interface between the Australian Plate and the subducting Pacific Plate, is investigated using the traveltimes of direct and converted seismic phases from local earthquakes.

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

open access: yesDeep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Major methods of seismic anisotropy

open access: yesEarthquake Research Advances
Seismic anisotropy reveals that seismic wave velocity, amplitude, and other physical properties show variations in different directions, which can be divided into lattice-preferred orientation (LPO) and shape-preferred orientation (SPO) according to its ...

Seismic Waves

open access: yes, 1939
The thesis consists of two parts. The first part deals with the historical development of the science of seismology and the application of the mathematical theory of elasticity to that subject. In the beginning m brief sketch of the method of determining the velocity of body waves at various depths inside the earth is given and the major ...
