INVESTIGATION OF EXISTING PILES USED IN RECONSTRUCTING LARGE LOGISTICS WAREHOUSE

Abstract

In reconstructing the large logistics warehouse with using existing piles, the piles were investigated. The pile diameter and reinforcement arrangement were as designed, and almost all the piles had no crack. The soundness evaluation by the author’s method was equivalent to that of conventional method. The compressive strength was larger than the designed value, and the neutralization depth was smaller than the designed cover thickness. The embedment in the bearing layer was confirmed by the comparison between the core boring through the pile and the standard penetration test. The magnetic exploration was effective on the evaluation of pile length.
