Chow, S. H., Diambra, A., O'Loughlin, C. D., Gaudin, C. & Randolph, M. F. (2020). Consolidation effects on monotonic and cyclic capacity of plate anchors in sand. Géotechnique 70, No. 8, 720–731, https://doi.org/10.1680/jgeot.19.TI.017. The following typographical mistakes have been identified. First, in Table 2, the first four entries in the column headed V are incorrect, as is the final footnote; the correct table is follows.

For ease of reference, tests are identified as LvP(n), where
- (a)
‘L’ denotes the loading type (M for monotonic loading, IC for irregular cyclic loading)
- (b)
‘v’ denotes the monotonic loading rate (v = 0·3 to 30 mm/s) or the peak cyclic load ratio (CLRpeak = q/qu = 1 or 1·25)
- (c)
‘P’ denotes the pore fluid (D for dry, W for water, M for methocel)
- (d)
‘n’ denotes the test recurrence (‘1’ for the first test, ‘2’ for the second test etc.).
PPT and/or accelerometer data lost due to damaged cable.
Test stopped due to actuator hitting displacement limit.
Drained monotonic and cyclic test results for a plate anchor with similar geometry (except ta = 2·75 mm) in dry dense sand.
Finally, in the section headed ‘CONCLUSIONS' (on p. 729), the sixth sentence is incorrect; the correct sentence is as follows.
Indeed, cavitation was not observed (at least adjacent to the anchor) since the maximum negative excess pore pressure was only about 20% of the theoretical cavitation.
The authors apologise to the readers of Géotechnique for these mistakes in the original paper.
