Determination of The Critical Embedded Depth Of Cantilever Pile Retaining Wall Using Physical Modeling Technique

Excavation and supporting systems have been always of challenging issues in civil engineering practice. In this article, the behavior of one widely used excavation supporting system called Contiguous Bored Pile (CBP) retaining wall is studied using physical modeling technique. Embedded depth of pile is a fundamental design parameter attainable in design phase and it is known that the wall displacement decreases with increasing pile embedded depth. But what is remained unknown and is meant to be revealed in this article is that to what extent increasing wall embedded depth can be effective. Critical embedded depth of pile is the minimum embedding depth at which the maximum efficiency of pile arises. Based on observations, the critical embedded depth of cantilever wall in granular soil is 1.2 times of wall height. It is worthy to note that the results of this study is not only applicable to all types of cantilever retaining walls, but also to the piles under lateral loading.
