Sheet piling is an earth retention and excavation support technique that retains soil, using steel sheet sections with interlocking edges. Sheet piles are installed in sequence to design depth along the planned excavation perimeter or seawall alignment.
Replication (statistics) In engineering, science, and statistics, replication is the repetition of an experimental condition so that the variability associated with the phenomenon can be estimated. ASTM, in standard E1847, defines replication as the repetition of the set of all the treatment combinations to be compared in an experiment.
A definition of reliability may be Yielding the same or compatible results in different clinical experiments or statistical trials (the free dictionary). Research methodology lacking reliability cannot be trusted. Replication studies are a way to test reliability.
