The cantilever retaining wall with shelf is one of the special types of retaining walls. High reinforced concrete retaining walls may be used economically by providing relief shelves on the back fill side of the wall. Such walls are termed as the retaining wall with relief shelf.Providing one or more relief platforms or shelves, extending them to the rupture surface have an advantage of decreasing the overall lateral earth pressure on the wall and increasing the stability of the structure. This results in an economical design because less material goes into the wall as compared to massive structure of cantilever or even counterfort retaining walls without shelves. The study of such type of retaining wall is therefore important to see its performance. This type of wall is some what un-noticed structure. Very few literature is available on this type of retaining wall. This book presents an experimental study performed on a steel plate model of retaining wall (IMRW) with and without shelves. The book includes the structural design and a computer program for cantilever retaining wall and retaining wall with single shelf too. This book will be helpful to the researchers in this field.
