Drilled and Grouted Micropiles: State-of-Practice Review. Volume 1. Background,Classifications, Cost

摘要

Micropiles are small-diameter, drilled and grouted reinforced piles used for bothstructural support and in situ earth reinforcement. They were conceived in Italy in 1952, but have become popular in the United States only since the mid-1980's. This report provides a comprehensive state-of-practice review, drawing on data from an international basis. This Volume I provides a general and historical framework and new classifications of a type and application. Cost and feasibility are also discussed. Volume II deals with the design of single piles, and groups and networks of piles. Volume III reviews construction, QA/OC, and testing issues, while Volume IV provides summaries of 20 major case histories illustrating the principles and procedures of volumes I, II, and III.
