| Abstract: | According to construction experience, this paper introduce the techniques of the vibro-percussion, pipe-sinking and double-poured piles embedded expansion on the sand-pebble alluvial terrace. Then the technological process and working principles are given. The bearing capacity of a single pile by analyzing three experiment piles on the construction spots are also discussed, and a calculation formula of the bearing capacity is presented for reference. |
