Soil structures such as water channels and earth dams, in spite of their advantages, are considered as high risk structures. These structures are often faced with irreparable cultural, social and economic losses against natural factors such as floods. In the meantime, design engineers have long been seeking measures to prevent the destruction of earth structures, while increasing the shear strength of earth's materials. One of the ways to increase soil resistance is to add mixed materials to the soil with high shear strength. So far, materials such as Bentonite, polymeric and chemical materials, vegetable fibers, etc. have been used and tested. In the present study, it has been attempted to study the effects of these materials on soil properties through the use of nano-materials called Montmorillonite, combining interdisciplinary nano science with geotechnical science. For this purpose, nano materials are mixed in five levels with the soil used in the earth's dam, and it shows an increase of about 70% of the shear strength of the soil for adding 5% nano particles to the soil. In the rest of the experiments, the remaining soil properties from the perspective of geotechnical science have also been studied, which is discussed in detail in the conclusion and discussion of the results.
