Challenges and solutions to model-scale testing for composite deep foundations and existing foundation enhancement

Laefer, Debra F. ; Manke, Jonathan P. ; Tucker, Jason E. ; Batten, Yuri (American Society of Civil Engineering (ASCE), 2007)

Laboratory testing for foundation design offers advantages over field-testing, especially, where existing installations preclude easy accessibility. Advantages include a homogeneous soil, ability to place instrumentation ...
Grouting patterns and possibilities with helical piers

Laefer, Debra F. ; Menninger, Nicole E. ; Hernandez, William E. (American Society of Civil Engineering (ASCE), 2005-05)

The experimental procedures and results are presented for a one-tenth scale laboratory investigation of changes in achievable grouted zones through alterations in helical pier parameters. The parameters investigated were ...
