Figure 13.
The panel a has 4 graphs with V prototype in meganewtons from 0 to 20 against displacement ratio from 0 to 0.20 per cent. Pre-installed buried at 50 g rises from 0 to about 12.5 meganewtons. 1 g jacked at 50 g rises faster and reaches about 17.5 meganewtons. Pre-installed buried at 100 g rises from 0 to about 12.5 meganewtons, with centrifuge test values reaching about 12.7 before a drop near 0.15 per cent. 1 g jacked at 100 g rises from 0 to about 17 meganewtons, with centrifuge test values reaching about 16.8 before a drop near 0.15 per cent. Panel b has 4 graphs with V prototype in meganewtons from 0 to 5 against displacement ratio from 0 to 0.3 per cent. Pre-installed buried at 50 g rises from 0 to about 2.6 meganewtons, close to the dashed w y divided by 50 line. 1 g jacked at 50 g rises from 0 to about 4.3 meganewtons, close to the dashed w y divided by 50 line. Pre-installed buried at 100 g rises from 0 to about 2.6 meganewtons, with the centrifuge test fluctuating near 2.5 to 2.7 after 0.18 per cent. 1 g jacked at 100 g rises from 0 to about 4.2 meganewtons, with the centrifuge test fluctuating near 4.0 to 4.3 after 0.2 per cent. Curve fitting and centrifuge test lines follow similar rising trends across all graphs.Curve fitting of the simplified analytical model to the experimental results at prototype scale, comparing the various installation methods at two different g-levels: (a) response in compression and (b) pull-out response
