Abstract

This paper presents a case study example of appropriate method selection of stabilization and reinforcement of slope by introducing engineering and economical aspects. Introduced slope is located in science and research campus of Islamic Azad University (IAU) in north of Tehran with height of 4-29 m and length of 370 m. A big building with 9 floors and total area of 70000 square meters is located upper and near edge of slope, so that existence of this building has increased sensitivity of projects design and construction method. Slope is located in vulnerable area with a high risk of seismicity based of 6th Iranian building code. In addition primarily geotechnical site investigation is reported existing of 13 different geotechnical zones of rock mass with R.Q.D less than 10% and slope wash and fill material. A second expanded series of site investigations program have been performed to obtain better geotechnical resolution and information about slope. In this project, in addition of stabilization of slope, architectural aspects of slope’s stabilization system was very important, so that, capability of green face for slope and vegetate of small trees and grass in berms introduced in design, in addition slope should have a compliance with vicinity of existing project. By introducing of seismicity of project location and economy, stabilization and reinforcement of slope by geogrid material is selected for this project in comparison other excising methods. More detailed information about geological and geotechnical of site condition are presented in paper.

Stabilization and Reinforcement of Slope With Geogrid: A Case Study

Chicago, Illinois

This paper presents a case study example of appropriate method selection of stabilization and reinforcement of slope by introducing engineering and economical aspects. Introduced slope is located in science and research campus of Islamic Azad University (IAU) in north of Tehran with height of 4-29 m and length of 370 m. A big building with 9 floors and total area of 70000 square meters is located upper and near edge of slope, so that existence of this building has increased sensitivity of projects design and construction method. Slope is located in vulnerable area with a high risk of seismicity based of 6th Iranian building code. In addition primarily geotechnical site investigation is reported existing of 13 different geotechnical zones of rock mass with R.Q.D less than 10% and slope wash and fill material. A second expanded series of site investigations program have been performed to obtain better geotechnical resolution and information about slope. In this project, in addition of stabilization of slope, architectural aspects of slope’s stabilization system was very important, so that, capability of green face for slope and vegetate of small trees and grass in berms introduced in design, in addition slope should have a compliance with vicinity of existing project. By introducing of seismicity of project location and economy, stabilization and reinforcement of slope by geogrid material is selected for this project in comparison other excising methods. More detailed information about geological and geotechnical of site condition are presented in paper.
