Abstract

The Nailed-slab pavement system can be analyzed by using equivalent modulus of sub grade reaction. This modulus consists of modulus of subgrade reaction contributes by slab and additional modulus of subgrade reaction contrib utes by pile which installed under the slab. The displacement on the surface of loading plate is always larger than the relative displacement between pile and soil. Since the relative vertical displacement between the pile and surrounding soil is very smal l, ultimate pile shaft resistance has not been fully mobilized yet. The mobilized unit pile shaft resistance can be reduced by applying dispalcement factor. Some researcher conducted small scale test and others conducted full scale test. This research is a imed to study the effect of different model scale to the dispalcement factor. Results show that the model scale affects the value of dispalcement factor. Displacement factor for full scale model very small than small scale model. In other case, pile length can also affect this factor
