Study on capacity of single pile subjected to surrounding soil’s settlement
Piles driven to clay are often subjected to surrounding soil’s settlement due to consolidation and second consolidation of soft soil. Since surrounding soil’s downward movements are larger than piles’s, negative skin friction develop develops on the piles’ shaft. The drag force caused by negative skin friction may be large enough to reduce the pile capacity or to overstress the pile’s material. The maximum axial load and settlement of pile foundation are also affected. Thus, we need to take more consideration of this issue.This study was undertaken to accomplish the following objectives:First, determine the position of neutral plane in soft soil condition in consideration of surrounding soil’s settlement and axial load. Analyse rate and tendency of neutral plane’s movement. Second: new design charts and procedures are presented to estimate the capacity of pile in consideration of negative skin friction and the mobilization of skin friction in the vicinity of neutral plane.
