Experimental Study on Factors Influencing Isolation Effects of Isolation Piles Subjected to Surcharge Load

The paper aims at analyzing the factors which contain length and diameter of isolation piles, pile spacing and the distance S1 between isolation piles and settlement-reducing piles, influencing isolation effects of isolation piles under surcharge load. The results summarized by eight laboratory model tests show that the maximum axial force and bending moment of settlement-reducing piles tend to decrease with the increasing length or diameter of isolation piles or with the declining pile spacing. Meantime, the length of isolated piles plays a significant role in diminishing the bending moment. The isolation effects of axial force and moment can be neglected when pile spacing reaches 8D. Apart from that, the isolation effects for axial force could be enhanced while diminishing the distance S1. However, impacts on the moment isolation effects are not significant subject to the variation of distance S1. This investigation could provide a good reference for the design and application of isolation piles.
