Influence of pin piles entrenched in clayey and sandy soil

Abstract

Pin piles have been principally utilized to uphold components of footing to counteract the static and dynamic loadings. Pin piles have been utilized adequately in numerous uses of ground improvement to increase the bearing capacity of soil. The purpose of this study is to observe the behaviour of different types of soil when pin piles were inserted in the vicinity of square footing. The diameter of pin pile, edge distance and pile to pile distance were taken as variables to study the effect of pin pile. Both the soil behaves differently to the pin piles. Although, the insertion of pin piles in clayey soil is difficult but as clays are sensitive to the settlement the pin piles can play a vital role in improvement in load bearing capacity even inserted up to shallow depth. Pin piles also show significant improvement to restrict the lateral movement of cohesion less particles of sandy soil. This paper holds the comparison of both clayey and sandy types of soil subjected to pin piles insertion in the periphery of existing footing through a laboratory model.
