study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. the process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. by means, abaqus software was applied for the finite elem...

The earthquake-induced displacement of sloping soil mass is an important indicator co-seismic landslide initiation. In this paper, improved Newmark model that considers the accumulation dynamic pore water pressure (DPWP) in caused by both vertical and horizontal ground motions proposed. can quantitatively describe changes seismic yield acceleration near-saturated infinite slopes. Three differen...

Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...

Satellite Laser Ranging (SLR) measurements of the Earth’s gravity field can be used to solve for solid Earth tides. We use those solutions to place constraints on anelasticity in the Earth’s mantle at periods of 12 hours and 18.6 years. The results imply that the anelastic parameter Q is smaller for those tides than for seismic waves. We interpret this as evidence that Q is frequency dependent....
