Experimental and Numerical Study of the Effect of PET Recycling Admixtures on Pore Water Pressure and Output Discharge in Homogeneous Earth Dams. Ahmad Zadeh Touri R., Pourbakhshian S., Pouraminian M. J. Civil Eng. Urban., 5(1): 31-34, 2015; pii:S225204301500007-5 Abstract This study analytically and experimentally investigates the leakage in homogenous earth dam (clay) reinforced by recycled PET. First, the effect of PET addition on permeability of clay in geotechnical laboratory is evaluated, according to the results of first step, a physical model of homogenous earth dam is prepared in laboratory flume, both in PETs or without PETs and measured the water height in dam body using piezometers installed on flume body and also leakage discharge was calculated. Third, phreatic line formed in the body of dam and the pore pressure of it was analyzed regarding the first and second phases. The impact of output discharge reduction on dam stability was also studied in software; PET addition impact on output discharge reduction was 23.14%. Discharge reduction lead to increase of dam stability. Keywords: Homogenous Earth Dam, Permeability Test, Physical Model, PLAXIS, PET [Full text-PDF] منبع: [Hidden Content] J. Civil Eng.
