- Abstract
- Two - row Overlap Pile wall is a novel retaining wall system with high flexural rigidity and waterproofing for deep excavation support currently being developed in Korea. The Two - row Overlap Pile wall is constructed by making an overlap between consecutive four - axis (or two - axis) auger piles which themselves are overlapped and arranged in zigzag manner. In this study, the flexural rigidity of the Two - row Overlap Pile wall, including the effect of cross - sectional shape, was examined using both theoretical and numerical approaches. The results of investigation suggested that the Two - row Overlap Pile wall formed with two - row piles exhibit greatly higher flexural rigidity than conventional one - row pile walls such as Cast in place pile (CIP) and Secant pile wall (SPW), whereas the effect of overlap length between piles on the flexural rigidity is relatively minimal.
