This paper discusses the behaviour of single aluminium pile embedded in M-Sand under lateral loading by finite element software using Abaqus/CAE 6.14. This study was carried out for the  different pile embedment lengths based on length to diameter ratios (L/d) 23,28,33. This study includes the effect of embedded pile length on lateral deflection of pile, lateral load capacity of pile ,horizontal modulus of subgrade reaction of M-Sand due to lateral loading of pile. From the study, It is concluded that the lateral deflection of the pile decreased with the increse of embedded pile length due to the passiveness of M-sand for same lateral loading. The lateral load carrying capacity of the pile was increased with the increse of pile length for same deflection about the half of pile diameter. The horizontal modulus of subgrade reaction was incresed for a minimum strainig of the pile during the lateral loading. This horizontal modulus of subgrade reaction plays a vital role in the design of foundation. It is concluded that for a minimum lateral displacement, the horizontal modulus of subgrade reaction increases the bearing pressure of the soil.
