Anamur – Kaledran Devlet Karayolu İnşaatında Açılan Derin Yarmaların Şev Stabilitesi Açısından Değerlendirilmesi

Abstract

This study aims to assess the stability problems on the deep cut slopes created in overjointed schist and locally landslided areas according to the geological and topographic effects and to improve suitable engineering solutions.Within the scope of studies, to deteminate geological and tectonic properties of the study area, topographic and geological mapping studies taken in four troubled cut slope region. To determine main values of slope design, the parameters provided from field investigation database and the parameters provided from back-analyses solved in geometrically identified landslide sections compared. With achieved and corelated parameters, these four problematic cut slopes are redesigned. As the result of all these assessments; it s established that the GSI values obtained from field works and GSI values obtained from back-analyses have a intense uniformity. Therefore, it s understood that the new design of slopes with these GSI parameters present successful performance.
