Effect of Geotextile Layers on Earth Dam Stability during Earthquakes

Earthen dams are sometimes built with large dimensions in order to produce electrical energy, control floods, supply drinking water and agriculture, etc. The greater the angle of internal friction between soil particles, the more the shear resistance of soil improves. As a result, the stability of dam increases. The issue of increasing the shear strength in the soil with using geosynthetics in the earth dam is the main goal of this research. The effect of geosynthetics and their arrangement, placement distance from each other, length, and materials used, including cohesion, unit weight and internal friction angle are the main research variables. For this purpose, Plaxis software has been used.
