A Study Geotechnical and Engineering Geology of landslide Galevarz and occurrence of its effect on Gazvin-Rasht highway

A survey in nourthern region of Iran and apart of new highway between Gazvin-Rasht under struction achieved which because of passing Alborz mountain, it is not safe locationally, so that it can caust the landslide and rockfall in length of highway. Some of them are old and inactive while others are active. 13 of these happened between Rudbar and Rostamabad regions of highway. Out of them, 6 accidents old and the vest are yang. The focus of our studies was located over the new landslides inside the region of Galevarz village. The vastity of this landslide is 180 meters long, 170 meters wide and about 15 meters depth. The landslide happened over the alluvial sediments, weak contacts, irrigation of upper part of the oliv gardens and rainwater channels in alluvial deposits can be important factors of this landslide according to studies conducted one choice for. According to studies conducted one choice for, 8 meters vertical walls by 1 meter horizontal flats can be controlled Galevarz landslide and some drainage system is made above landslide to control it. In the future, instability in highway will occur drainage and also, in upper part can be effective in control of the landslide.
