Assessing on the Geotechnical Problems Which Causes for the Road Failure from Gilgel Beles to Bahir Dar Road Segment

Abstract

Geotechnical problems such as problematic soils (expansive soil, organic soil, natural collapsible soils, etc.), problematic rock (shale, weathered limestone), soil slope instability and rock slope instability or rock fall (landslide) which damaged civil engineering structures, such as roads, buildings, dams, railway, and other related structures in Ethiopia. The research was conducted by identifying the geotechnical problems and its effects on road segments in the north west part of Ethiopia, specifically along Gilgel Belles – Bahir Dar road segments. Gilgel Beles – Bahirdar road segment which passes on the hilly and mountainous terrain are characterized by variable topographical, geological, hydrological and land-use condition.
