ABSTRACT: The moisture content of the soil around foundation piles plays an important role in the load transfer characteristics of interfaces between the soil and the pile. In this paper, the effect of the soil moisture content on the shear strength of an interface between a soil mixture (kaolin-sand) and a steel plate is investigated. Direct shear type interface tests are performed. For the purpose of comparison, the shear stress versus displacement behaviour of the soil mixture alone is also examined. The friction angle and adhesion at the interface are determined as a function of the moisture content of the soil. The analysis of laboratory results is extended to determine the shaft resistance of a pile.
