Abstract
The use of drains in a regular grid and required depth in the soil are reduced the time of drainage process and soil consolidation considerably. Sombar dam is a project to use optimum seawater flow and flood control to provide agricultural water as well as to develop the area under cultivation of the existing dam in Gholaman village as well as the city of Raz in north Khorasan province, Iran. The purpose of this research is assessing the influence of vertical geotextile drainage (length and spacing), for different permeability ratios (ky/kx), on the dam stability during the construction using GeoStudio2012 software. The analysis is performed using models of Mohr-Coulomb and modified cam clay. The results show that there is a significant effect of the drains for the studied parameters. After 24 months with maximum drain depth (24m) and minimum drain spacing (2m) the values of the studied parameters are closer to each other.
