Abstract

Soil structure and void ratio are the major factors that control the permeability changes during soil deformation. In this research, we proposed and tested a conceptual model considering these two factors based on the concept of permeability anisotropy. This model, which is expressed as k(e) graph, determines the total k values that soil can achieve and shows that as deformation proceeds, soil permeability passes through a specific zone in the k(e) graph. Thus, by deforming a soil sample, measuring its permeability during deformation, and comparing the results using the k(e) graph, it might be possible to predict deformation effects on the permeability. To evaluate this conceptual model, we designed and built a special apparatus to carry ou

Abstract

This study is a revised inventory of landslides triggered by the Rudbar-Manjil earthquake (Mw= 7.3), 1990, obtained through the study of Komak Panah and Hafezi Moghadas (1993), interpretations of the stereoscopic aerial photos, and field data. We mapped the 223 coherent landslides with a total area of 11.3 km 2 and a calculated volume of 3.8? 10 8 m 3 using a digital elevation model (DEM, 12.5 m) within the geographical information system (GIS) software. The correlation between landslide occurrence (size and distribution) and the controlling factors was analyzed using the bivariate model and the linear automated modeling (LINEAR) procedure in the SPSS software. Both LINEAR models of landslide volume (LV, m 3) and landslide area (LA, m 2) in

Abstract

The twin Ahar-Varzeghan earthquakes (Mw = 6.4 and Mw 6.2, August 12, 2012) are among the most severe and destructive seismic events to have occurred in the northwest part of Iran in the last century. The main shock of this event was felt within a 300?km radius in most of the northwest provinces of Iran, including West Azerbaijan, Ardebil, Gilan, Zanjan, Alborz, Hamedan, and Kurdistan, as well as in neighboring countries such as Republic of Azerbaijan, Armenia, and Turkey. The quake caused some large landslides, which led to remarkable economic losses in the region. Landslide susceptibility mapping is one of the useful tools that can be applied in disaster management and planning development activities in mountainous areas. In

Journal PapersAsian Journal of Geological Research , 2019 March 30, {Pages 14-Jan }

Abstract

In this research, structures, geometries and directions of dominant stresses in the Abbar region (northwestern Iran) were examined. The fractures and lineaments of the area adequately matches to the brittle left-lateral shear zone model, and the two main fault systems of the area correlate with the P and R2 orders in the shear zones, respectively, where shear occurs along an approximate S60E direction. Prior to the Quaternary, a compressive tectonic regime has governed the Abbar region along the NW-SE direction. Since the early Quaternary, this regime has changed to left-lateral shear along the WSW-ENE maximum stress direction. Thus, the reverse faults of the old regime have converted to strike-slip faults with reverse components. The geomo

Abstract

The relation between Soil compression degree and the permeability changes during static compression process is one of the important factors for understanding hydro mechanical soil behavior. In this research such relationship? has been closely studied. Three soil samples have been selected from loess soil (wind deposits) that extended widely in Golestan province, north eastern Iran. In first step, a test apparatus must? be design to measure the soil compression degree and permeability value simultaneously. The designed apparatus? is able to set high porosity soil sample in a test cell, measurement static compression force, compression degree? and the value of permeability at different stages of soil compression process. In addition,? soil st

Abstract

The Behabad region is located within a tectono–sedimentary zone in southeast Yazd province, Central Iran. The tectonic activities have deformed and faulted the Mesozoic and Quaternary formations in this area. The faults in Kuhbanan and Behabad have played a key role in the evolution of geological events, mineralization, and the formation of Behabad–Kuhbanan horst. These faults have separated the Posht-e-Badam block from the Tabas block and the Behabad zone from the Abdoghi–Ravar tectonic zone, respectively. Remote-sensing techniques and field observations show that the Pb–Zn veins share similar trends with the structures. The compressional system induced by the activities of the Behabad-1 and 2 fault systems have caused the formatio

INVESTIGATION ON THE MECHANISM OF SAEIN STRAIT LANDSLIDE (NIR-SARAB ROAD) IN REGARD TO THE HYDROLOGICAL AND GEOMORPHOLOGICAL CONDITIONS

Abstract

Saein Strait landslide took place along Nir-Sarab Road by the southern flank of Sabalan volcano on June 6, 2005, and damaged 350 m of the main road. The main factors which might affect the stability of this particular slope are the thickness and texture of the soil, extensive weathering, gentle slope to cause the accumulation of the material, and finally the regionally affected groundwater level fluctuations. A research was planned based on the field studies, laboratory tests and numerical modeling to identify the main factors affecting the stability of this slope. Landslide profile and engineering geological properties of materials were applied in the numerical models. The effect of rainfall in soil saturation process was simulated for 35

Abstract

Rainfall induced landslides result in economical losses and casualties all over the world anualy. The main triggering factor of shallow landslides and debris flows in the rainy Province of Mazandaran (northern Iran) is the rainfall events. This study investigates the landslides triggered by rainfall throughout the watersheds of Tajan and Nekarud rivers. Twenty three recorded rain events occurred during the October 2012 to March 2013 in the eastern Mazandaran. Out of the 23 rainfall events during this 6-month period, 15 short to middle rainfall resulted in slope failures. Intensity-duration (ID) of the rainfall events which induced landslides and debris flows were plotted in logarithmic scale. The threshold of ID was determined for those rai

Abstract

An unlikely combination of relatively low rainfall intensity and gently sloping topography produced numerous landslides and debris flows during a prolonged storm in July 2006 around Okaya City, Nagano Prefecture, Japan, and indicated the existence of other factors contributing to the landslide initiation. We focused our detailed investigation on a relatively large landslide/debris flow near Okaya City where the highly variable soil characteristics in the landslide scarp led us to examine the variability of physical and hydrological properties throughout the soil profile and within the area above the landslide. The soil in our study area ranges from gravelly loamy sand to loamy silt and is the result of ≈?10,000?years of erosion processes

Abstract

Population growth and human activities as its consequence, development of residential zones, life lines such as power lines, water canals, gas and oil pipelines, and road construction, bring the population close to mountainous areas. Unfortunately, due to lack of detailed study of slope stability the number of landslide events triggered by earthquakes and heavy rainfalls has increased in such regions. In 1990, Fatalak landslide (north-western Iran) triggered by Roudbar earthquake caused 173 casualties, and in 1998, Abikar landslide (western Iran) in Chahar-Mahal Province caused 53 casualties after a heavy rainfall period (Shoaei and Ghayoumian 1997). Predicting the time to failure in susceptible slopes and evaluating the risk o
