Case Study of the Characteristics and Mechanism of Rock Burst near Fault in Yima Coalfield, China
Shock and Vibration, 2021 Deep mining near faults may easily cause rock bursts, which seriously threaten mining safety. Based on the engineering background of deep mining near fault in Yima coalfield, by collecting the rock burst events that happened near fault during deep mining,

Comparison of wind turbine tower failure modes under seismic and wind loads [PDF]
, 2019 This paper studies the structural responses and failure modes of a 1.5-MW horizontal-axis wind turbine under strong ground motions and wind loading. Ground motions were selected and scaled to match the two design response spectra given by the seismic ...

Slip‐weakening distance estimated at near‐fault stations [PDF]
Geophysical Research Letters, 2007 We estimated the slip‐weakening distance from the seismograms recorded at near‐fault stations, considering the effect of spatio‐temporal filtering for a continuous propagation of rupture. This effect is usually observed at some distance away from the fault. We used a Green's function for 2‐D anti‐plane rupture propagating with constant rupture velocity

Co- and post-seismic vertical displacements of Wenchuan Ms8.0 earthquake near Beichuan
Geodesy and Geodynamics, 2011 Co- and post-seismic vertical displacements of the Wenchuan earthquake derived from two measurements in 2008 and 2010 along two partly-damaged leveling lines near the epicenter show the following features: Co-seismic displacement at Beichuan-Yingxiu ...

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]
, 2014 The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...

GPS source solution of the 2004 Parkfield earthquake [PDF]
, 2014 We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (

Seismic analysis of a tall metal wind turbine support tower with realistic geometric imperfections [PDF]
, 2016 The global growth in wind energy suggests that wind farms will increasingly be deployed in seismically active regions, with large arrays of similarly designed structures potentially at risk of simultaneous failure under a major earthquake.
