Abstract
Due to the fact that the design and implementation of earthen dams is increasing day by day in the country and it is considered one of the basic needs of the country, and any instability in earthen dams, in addition to being part of the country's infrastructure, causes a lot of damage. The structures built in the water flow path are behind the dam, so the stability control of these types of dams is of great importance in this research.Investigating The Effect of Drainage Parameters of Parsian Earth Dam on Stability of Dam SlopesIt has been investigated by using Geostudio2D 2020 finite element software. In this research, firstly, accuracy assessment has been done Geostudio 2D 2020 software, and then the effect of horizontal drain, vertical drain, combined drain, the effect of water height behind the dam, drain length has been investigated. Horizontal, vertical and combined, changing the ratio of length and height of horizontal, vertical and combined drains, According to the investigations, the results show that the use of horizontal, vertical and combined drains has increased the stability coefficient of the dam roof, and combined, vertical and horizontal drains have had the greatest impact on the stability coefficient of the dam roof, respectively. The effect of the existence of horizontal, vertical and combined drains on the stability of the studied dam's top. The results show that the use of the studied drain has an average effect of 24.87% on the stability of the dam's top.
