The Peak possible ground acceleration of the earthquake and its effect on the slope Stability in the Komrud village semi dynamic method (northern Semnan province)
Abstract:   (1864 Views)

Komrud village of located on the slope is particularly susceptible to landslides. The slope stability analysis is of special importance because of landslides or slope failures can cause major damages life and financial. In studies to determine the factors and parameters affecting the slope is unstable. According to studies, one of the most important factor affecting landslides in this area is the force exerted by the acceleration of the earthquake. With this approach, the maximum possible acceleration of earthquakes in a 50-year period is estimated at the site. On the other hand, based on studies of the geological is determined profile of the slope geometry, physical and resistance parameters to the landslide susceptible. Then using the modeling software in FLAC 2D 5.00 elasto-plastic structural models, with failure criteria Mohr – Coulomb, stress-strain behavior of the soil has been examined to pseudo-dynamic method. A base position at the top of the slope is considered and displacement it horizontally to reach the maximum possible acceleration is calculated and recorded. The results of this study indicate that Horizontal displacement followed the landslide, can be occur below the maximum acceleration estimates.
