Cracks of irrigation channel’s service roads are becoming a significant feature in Al-Ghab region. All information indicates that lateral spreading of stresses in slope vicinity induced cracks in the side parts of roads. These cracks resulted from la
teral displacements, which could dominate total displacements. This
paper presents a geotechnical evaluation of the possibility to mitigate this phenomena by using geogrid soil reinforcement. Finite elements numerical model analysis is performed to calculate total, horizontal and vertical displacements at road side near channel’s slope. Numerical models include different cases of
un-reinforced soil and geogrid reinforced soils at different locations. Locations of geogrid were chosen carefully to attain the best effectiveness. Beneficial factor and coefficient of efficiency were determined for reinforced road.
In 2002, Zeyzoun Dam failure, that is an embankment dam located at the northwest of Syria, made a big Awareness of the effects of the lack of Geotechnical investigations and concern given to seismic design, geological conditions and location of the d
am. Zeyzoun dam location, in the vicinity of the Dead Sea fault system, emphasizes the importance of analyzing the effects of lithological stratum in dam foundations on dam seismic stability. This paper is concerned with the influence of a high permeable soil layer that has different static and dynamic properties, and exists at different depths in dam foundation. Geo-studio software, a Geotechnical program that applies the finite element method and can consider analysis like seepage, dynamic analysis and slope stability, used to build and analyse numerical models. The results of dynamic analysis showed rising of phreatic line level in dam body, amplification in dam dynamic response, increasing in pore-water and excess pore water pressure and decreasing in stability factors of safety, along with decreasing of the thin layer depth.
