Abstract

In last several years periodic reports indicating damages toward resident;s homes due to ground movements in Barikan region, 120km far from tehran, have been issued. The earth movements are demonstrated by tension cracks and scraps on ground surfaces and walls of in site homes and gardens. Since the slow and continuous earth movements were observed in the site, a course of site investigation consisted of the monitoring of surface and deep earth movements has been considered to study the affecting factors and the extent of of landslide. In addition to ground movement measurements, by using the geotechnical properties of different soil layers, stability analysis of the soil mass was performed. Results showed that the village would be stable at static conditions in all relative groundwater levels. However, in case of earthquake with value of horizontal acceleration equal to 0.14g, analyses indicated total instability of the site. It seems that the movements, which apparently widen the cracks and damage the houses and walls of the gardens, are due to the mild in site earthquakes or accelerations of the farther occurred earthquakes of the area, which by reducing the F.S. of the slope, increase the severity of movements rate in the village. In this paper the results of conducted researches, as well as possible remedial solutions for ground movements, with regard to known effective factors of landslide, are presented.

Investigation and Treatment Analysis of Barikan Landslide

New York, New York

In last several years periodic reports indicating damages toward resident;s homes due to ground movements in Barikan region, 120km far from tehran, have been issued. The earth movements are demonstrated by tension cracks and scraps on ground surfaces and walls of in site homes and gardens. Since the slow and continuous earth movements were observed in the site, a course of site investigation consisted of the monitoring of surface and deep earth movements has been considered to study the affecting factors and the extent of of landslide. In addition to ground movement measurements, by using the geotechnical properties of different soil layers, stability analysis of the soil mass was performed. Results showed that the village would be stable at static conditions in all relative groundwater levels. However, in case of earthquake with value of horizontal acceleration equal to 0.14g, analyses indicated total instability of the site. It seems that the movements, which apparently widen the cracks and damage the houses and walls of the gardens, are due to the mild in site earthquakes or accelerations of the farther occurred earthquakes of the area, which by reducing the F.S. of the slope, increase the severity of movements rate in the village. In this paper the results of conducted researches, as well as possible remedial solutions for ground movements, with regard to known effective factors of landslide, are presented.
