Application of Composite Pile Foundation in Sea Embankment Foundation Treatment
For seawalls in coastal development plots,the red line behind the seawall is close to the foot of the inner slope of the seawall with a large load,while the sea area in front of the seawall does not allow for stone throwing and compaction.Therefore,it is difficult to solve the overall stability problem by simply using conventional pile foundation treatment method for bored piles on seawall body.After construction,the structure will be detached due to severe uneven settlement between the seawall body and the backfill soil behind it.Based on the case of Lingkun North Section Standard Embankment(Phase Ⅱ)Project in Wenzhou,through calculation and analysis,the composite pile foundation of bored pile for the seawall body combined with cement mixing pile for backfill soil as transition treatment is used in construction.The application shows that the composite pile foundation is effec-tive in enhancing the overall stability of the seawall and dealing with uneven settlement,providing reference for similar foundation treatment in coastal areas.
