چکیده مقاله:
Soil-cement is a mixture of Portland cement, soil and water, which are bonded together due to the cement hydration and compaction, and have durability, low permeability and resistance against water. The International Committee of Large Dams (ICOLD) defines the soil-cement as a mixture of Portland cement soil and water, which due to the hydration and compaction, is bonded together and produces a durable compacted composition with low permeability and wear resistance. Numerical modelling, employing the commercial finite element software PLAXIS-۳D, of cofferdam of bakhtiari dam (in south west of Iran) made of soil-cement revealed its stability in this application. The results showed that stability of cofferdam in two situation (Dry and Saturated) is guaranteed. Due to the fact that this kind of dams have a high weight, it could be suitable for dams and hydraulic structures. Also design mixture of soil cement makes it economically very good option for embankments.
