Over the years seismic activity has been a relatively common cause of tailings impoundment failure The flow of liquefied tailings from such ruptures can result in very severe consequences including loss of life and environmental damage A co disposal technique consisting of placing waste rock inclusions in tailings impoundments prior to and during tailings
Seismic Effects of Blasting in Rock Dauetas Denisyuk Kuzmenko Vorobev CRC Press Jan 1 1993 Science 177 pages The results of theoretical and experimental investigations of seismic waves depending on natural and technological factors are discussed with methods for engineering calculations of industrial blast
In Section 4 taking a rock slope site overlying bedrock half space as an example the seismic effects for different slope height slope angle shear velocity and incident wave types are studied It is well established that the site effect of rock slopes containing the topographic amplification effect and the stratigraphic amplification
Thus the amplification effects resulting from both the vibrating soil structure system and surface topography were assessed based on seismic rock outcrop motions at various frequencies 2 Details of seismic recording and surface topography used in model calibration
Taking into account the seismic effect in rock mass classification is a relatively new topic which has been addressed in this paper Moreover it has been attempted to investigate the seismic
： The measured data of the engineering seismic effects induced by underground nuclear explosion were systematically analyzed and a consistent method for quantitatively representing deformation characteristics with a dimensionless characteristic energy
The destructive effects of seismic wave on the roadway surrounding rock in underground mine not only are influenced by failure mode and energy radiation of the source but also depend on the structure complexity inhomogeneity discontinuity etc of the coal

Seismic stability chart for 3D Hoek Brown rock slope A novel approach integrated tension cutoff and dynamic seismic effect March 2024 DOI / 4147543/v1
Rock pore structure is one of the important parameters in controlling both seismic wave velocity and permeability in sandstones and carbonate rocks For a given porosity of two similar rocks with different pore structures their acoustic wave speeds can differ 2 km/s and permeability can span nearly six orders of magnitude from mD to 20 D in both sandstone and limestone In this
To verify this hypothesis this work investigates the Chinese engineering rock mass classification system the basic quality BQ rating system considering seismic effects The main contribution of the current work is to quantitatively modify the rock mass intactness index K v in the BQ system considering the potential earthquake damage under various levels of design
The seismic response of the surrounding rock in crossing fault is a scientific problem involving many domains Song et al 2021; Yan et al 2020 Research on the dynamic response of crossing fault tunnel surrounding rock based on the time domain and frequency domain is beneficial for revealing the seismic response characteristics of surrounding rock from
The study presented hereinafter intends to shed light on the occurrence of the so called atypical topographic effects in the case of asymmetric rocky ridges Typical topographic effect defines the response of homogeneous rock hills when the morphology is the main factor that contributes to the ground motion amplification
In Section 4 taking a rock slope site overlying bedrock half space as an example the seismic effects for different slope height slope angle shear velocity and incident wave types are studied and the results are analyzed in detail To investigate the seismic response of rock slopes under actual seismic excitations three earthquake
geological site effects seismic velocity contrasts between material layers while topographic amplification plays a secondary role Burjánek et al 2010 2012 report strong localized amplification and polarization on fractured rock slopes which are interpreted to be caused by highly compliant tension fractures Moore et al 2011
The Swedish National Seismic Network SNSN recorded it as a moment magnitude MW seismic event which is considerably larger than any seismic event previously experienced at Kiruna and was
Barton 1984 describes the effect of rock mass deformation on tunnel in seismic region and defines the role of joints and water on tunnel stability Figueiredo and Assis 2018 describe the
Gei and Carcione considered the effects of pore pressure and partial saturation gas and water incorporating attenuation at all frequencies from the seismic to the ultrasonic band Therefore the TPB theory allows for the coexistence of water and free gas in the porous space which has been reported in several studies Milkov et al 2004
Natural freeze thaw FT cycles and earthquakes are two key triggers for landslides in cold regions However investigations on their coupled effect are rare In the current work this coupled effect was investigated by shaking table tests of two slopes namely a non freeze thaw NFT slope and a FT slope Results indicate that the slope s natural frequencies
