Worldwide use of micropiles has grown since their original development in the 1950s, and in particular since the mid-1980s. In general, micropiles are applicable when there are problems with using conventional deep foundation systems like driven piles, drilled shafts, or augercast piling. Micropiles are primarily used as elements for foundation support to resist static and dynamic loading conditions, and less frequently as in-situ reinforcements for slope and excavation stability. Micropile can be designed as soil frictional piles or rock socketed piles either under tension or compression. The advantages of micropiles are that their installation procedure causes minimal vibration and noise, they can be installed in difficult ground conditions, and they can be used in areas with low headroom and restrictive access. This makes micropiles the preferred choice of foundation system for retrofitting existing structures in challenging areas. This course is entirely based on the US Department of Transportation Publication No. FHWA NHI-05-039, Micropile Design and Construction. This two-part series discusses micropile classifications, design concepts, problems associated with the common installation methods, specifications, construction control and performance of this pile system. This is part two of the series.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
