The stresses caused by the traffic load on the canal embankments were investigated. Conventional
methods of slope stability provide a constant value of safety factor for the slope, providing no
information of slope displacements and possible variations of safety margins along the potential
failure surface. The design model admits the idea of a homogeneous, isotropic, continuous and
linear space that can be deformed. (Plaxis 2D) finite element program was applied to analyze the
slope stability of canals outer curve under traffic load. In this study four different conditions were
tested; Condition No 1: Dry condition, when there is no ground water in embankment and canal is
running at full supply level; Condition No 2: Dry condition, when there is no ground water in
embankment and canal is running at lowest water level; Condition No 3: Wet condition, at fully
ground water level in embankment and canal is running at full supply level; and Condition No 4: Wet
condition, at full supply ground water level in embankment and canal is running at lowest water
level. The embankment material tested for in-situ properties to clay and sand. And additional traffic
load above embankment is considered to estimate the worst case. |
