Reliability-Based Geotechnical Resistance Factors for Axially Loaded Micropiles
Micropiles are small-diameter drilled and grouted deep foundation elements used in various
applications that often involve superstructure or ground conditions where construction of other
foundation types is not practical.
The TRB National Cooperative Highway Research Program's
NCHRP Research Report 989: Reliability-Based Geotechnical Resistance Factors for Axially Loaded Micropiles
details the development of reliability-based geotechnical resistance factors for axially
loaded micropiles and related design specifications.
Supplemental to the report is an
Appendix.
