Abstract

One of the problems with peat soils, when subjected to imposed loads of construction, is the very high compression and long-term excessive settlement. The embankment can be built on peat soil, but it needs reinforcement that can contribute to increasing the stability of the embankment. The nailed slab system, as reinforcement, is expected to reduce settlement and increase the stability of peat soil. The aim of this paper is to study the effect of pile length and distance on the reduction of settlement in both monolithic and non-monolithic piles. The embankment load test was conducted on 70 cm x 120 cm plates, which were reinforced pile with different lengths and distances in the peat soil layer. The analysis was conducted on the reduction settlement of monolithic and non-monolith pile. The results showed that the length and distance of the pile had an effect on the reduction settlement. Changes in pile length are more dominant reducing settlement compared to changes in pile distance. Pile connection with slab has a significant effect on different lengths of piles than different distances piles.

Abstract

The Nailed-slab System is not a soil improvement method, but rather as an alternative method to improve the performance of rigid pavement on soft soils. The installed piles under the slab were functioned as slab stiffeners. This research is aimed to learn the behavior of Nailed-slab System under repetitive loadings and its consideration for practical application. 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 stiffeners which installed under slab. Piles and slab were connected monolithically, then in due with vertical concrete wall barrier on the two ends of slab. The system was loaded by vertical repetitive loadings. Results show that the installed piles under the slab which embedded into the soils were functioned as slab stiffeners and were able to response similarly in 3D. This system has higher resistance due to vibration. Thereby, the Nailed-slab system is promising for practical application.
