92AbstractOne of the problems in soil engineering is soil erosion by water flow Two main factors ofsoil erosion are generally wind and water Soil erosion causes soil loss to lose its functionalproperties Consequently to prevent such problems the soil should be protected fromerosion Soil conservation methods are divided into two categories including direct andindirect methods Among existing methods for soil conservation use of geotextiles dueto its easy implementation and economical advantages is an appropriate option In recentyears a product called textile concrete has been introduced to the market byresearchers which is a geocomposite made from a warp knitted spacer textile coatedwith a polyethylene film and filled by a cement paste One of the applications of textileconcrete is controlling soil water erosion in coastal areas In this research differentsamples of textile concrete were designed and manufactured Independent variables aretype of mortar fabric type fabric thickness time of erosion and the angle of settlementof textile concrete Three point bending test water erosion shear and impact tests wereconducted on the samples Moreover due to the long duration of the experiments aneural network system was used to train the data and to predict the erosion test results At the end in order to investigate the flexural behavior of the fabric the materialsstrength theories in bending behavior of sandwich panels were used The experimentalresults show that the use of mineral material additives affect the improvement of cementhydration such as glass powder and alumina which improve the flexural strength andresistance to sample erosion The use of glass powder increased flexural strength of thespecimens compared to the cement mortars Consequently it was concluded that erosionrate of samples were occurred in the initial time of erosion Keywords soil water erosion geotextile textile concrete neural network sandwichpanels
