بررسي خطر حركات دامنه اي و زمين شناسي مهندسي روستاي دولت آباد در شمال شرق رودبار

Mass wasting Hazard & Engineering Geology north East of Rudbar of Doulat Abad Villag

The region under study is located about 53 kilometers in the south the of Rasht, north west of the Ammarlu mountains, and north of Iran. Due to the field studies and the data obtained from the study of geological maps of the area it was revealed that the Doulat Abad landslide is on old one. Under study one of the effective environmental factors for ancient landslide in the region under study is the sefidrood river. Under study one of the effective environmental factors for Doulat Abad young landslide, have had the undeniable role with respect to the inherent conditions such as kind and tissue of material, uniformity direction water, slope, fault, hills shape, environmental factor. Three kinds of area were evaluated regarding the geology and engineering geology studies on the basis of suitable environmental and inherent factors. They inclued: 1- area that donʹt havy any landslide and instability or there is little landslide in them 2- area that have partial and are liable to landslide, and 3- area that have the danger of instability and serious landslide. The results of studies include 2 engineering geology map to the scale of 1:2000 and do rock mechanic examination that are presented with the solution for the stability of Doulat Abad landslide.
