Anti-slide Mechanism and Engineering Application of Small Diameter Steel Tubular Row Piles as Supporting Structure
摘要
Abstract
Through systematic study on small diameter steel tubular row piles as supporting structure, the antislide mechanism is proposed to be presented mainly as pile-soil composite structure acting as ＂analogous anti- slide piles＂, whereof the failure mode is that anchored section of tension member is pulled out, pile body of compression member is failed by bending and shearing, and compression strut is instable. On this basis, the technical details asdesign of such supporting structure are given, including definition of rows number, selection of pile spacing and row spacing, calculation of anchoring depth, and design of beams between piles. Small diameter steel tubular row piles are applied successfully at the embankment landslide along K78 ＋ 250 - ＋ 400 section of Guangyuan-Bazhong Expressway to ensure the safety and get good social and economic benefits.关键词
