摘要

Retaining walls are most widely accepted retaining structures owned in civil engineering fields like, transportation engineering, irrigation and bridge engineering. These walls are helpful in providing protection against landslides. This paper examines the failure pattern and safety factor of a t-type retaining wall (inverted), acted upon by gravity loading conditions, computed and simulated using computational software OPTUM G2. This analysis puts an effort to assess the effects of different components of such retaining wall like; length of heel plate (L1) and toe plate (L3), bottom plate depth (H2), cohesivity of soil (C) and internal friction angle (φ). The stability factor is found to be increasing with increase in length of heel and toe plate; as depth of bottom plate increases, safety factor shows increasing trend; similarly, as, soil cohesion and angle of internal friction increases, safety factor gradually increases. Shear dissipation pattern showing distinct Multiple failure surface has also been observed.
