Parametric Study Using FE Analysis of Cantilever Retaining Wall with Pressure Relieving Shelves
Retaining wall is a necessity in today’s infrastructure development projects. The construction works at hill sites or when there is difference in elevation of soil exists, earth retaining structures like cantilever retaining walls are required which often has limitation on height retained due to increase in soil pressure on the wall. For reducing the earth pressure on stem relieving shelves are provided. There are many research studies reported in literature for optimal location and designing shelves. Most of such analytical studies reported in literature have utilized FEM analysis using 2D elements. Also, there are reports of failures of retaining walls with shelves. Investigating causes of such failure needs proper forensic analysis and study simulating actual site condition in 3D domain. There is a need for analysis of Retaining wall considering the soil behaviour effect in all three dimensions. In the present study, the finite element analysis for cantilever retaining wall of 10 m high with relieving shelves, is performed by using 3D elements by varying number of shelves for different soil parameters. It was observed that the top displacement and the soil pressure acting on stem reduced with increase in number of shelves. A parametric study is performed using Midas GTS NX software using 3D elements which reveals the effect of number of shelves, on variation of unit weight and friction angle on deflection and earth pressure acting on the stem.
