Abstract: | Leaching of Lisan Marl, Dead Sea, Jordan increased the soil compressibility and cohesion intercept. Back analysis using the
Plaxis finite element code was successfully implemented. The Finite element modeling of dike construction showed a significant
increase of total settlement and negligible effect on the strength as calculated by the φ/c reduction method. The height of dikes to be constructed on Lisan Marl as foundation material, should be optimized to account
for the effect of soluble salts leaching. For this to take place, an accurate calculation of settlement is crucial. |
