Abstract:
Concentric loading on the Nailed-slab Pavement System causes stress in the soil and the inner forces in
structural elements. The load stress is transferred to the soil by the structural elements tends to concentrate in
the centerline area under the system. Since load stress is concentrated in the center line area, the soil stress and
inner forces can be higher in the center of the system. To reduce the soil stress and inner forces of structural
elements, the longer pile can be put in the center area of the system. This research is aimed to learn the
soil stress and inner forces behavior of the Nailed-slab Pavement System in case putting the longer pile in the
center area of the system. The maximum double wheel load was taken 50 kN which transfer to the slab surface
by contact pressure. Wheel load was loaded in the center of the slab. The Nailed-slab materials properties and
soft clay properties were taken from the previous researcher. The piles in the center area of the Naile
d-slab
were longer 33.3% than others. Results show that the Nailed-slab by longer piles in the center area can reduce
the soil stress significantly for maximum shear stress up to 28%. The inner forces were also reduced by about
43% to 46% and caused the reducing in lateral deflection of pile tip about 37%. It can be concluded that the
increasing pile length in the central area of the system can reduce soil stress and inner forces of the system.
