Abstract

The full scale Nailed-slab System was conducted on soft clay which consisted of 6.00 m x 3.54 m slab area with 0.15 m in slab thickness, 15 short micro piles (0.20 m in diameter, 1.50 m in length, and 1.20 m in pile spacing) as slab stiffener which installed under slab, piles and slab was connected monolithically by using the slab thickening (0.40 m x 0.40 m in area and 0.20 m in thickness), then in due with vertical concrete wall barrier on the two ends of slab. The system was loaded by vertical monotonic loadings. Loading positions were varied (i.e. center of slab, edge, and interior). Results show that the installed piles under the slab which embedded into the soils were functioned as a slab stiffener and were able to response similarly in 3D. The deflection experienced very small. Nailed-slab has linear elastic response until load 160 kN. Maximum deflection and bearing capacity were not significantly influenced by load positions. Nailed-slab System is promising for practical application.
