By Zhongxuan Yang, Richard Jardine, Wangbo Guo, Fiona Chow

A finished Database of exams on Axially Loaded pushed Piles in Sands stories the severe have to boost larger load-test databases for piles pushed in sands. the most important caliber parameters, inhabitants of present entries and reporting codecs are defined sooner than providing initial effects received from comparisons among axial capacities calculated by way of numerous predictive methods and placement measurements. This e-book additionally exhibits that the "simplified" and "offshore" ICP and UWA editions proposed via a few practitioners are over-conservative and that their use should be discontinued. the hot pile potential and stiffness database bargains a huge scope for comparing power prediction biases in relation to quite a lot of soil and pile parameters. Submission of extra prime quality assessments for inclusion in on a regular basis up to date models is encouraged.

  • Presents a accomplished and up to date database for piles pushed in predominantly silica sands
  • Features studies of the layout approaches for pushed piles in sand
  • Assesses the functionality of varied mainstreams layout approaches utilized for piles pushed in sand
  • Provides complete info of case histories of pile load tests

As shown earlier, the mean ICP predictions tend (on average) to become conservative for piles tested at ages exceeding 10–15 days.

1 Tests equipped with strain gauges and tension tests to failure are particularly valuable for isolating the shaft-to-base capacity splits from compression tests. offer information on driving method, pile embedment, diameter, tip end conditions, wall thickness, and material. Ideally, the pile driving records and pile age after driving should also be available. The database is then divided into a main set with pile ages of 10–100 days and a subset of tests conducted at both earlier and later ages.

However, as shown by Rimoy (2013) and Rimoy et al. (2015), base capacities show little or no variation with age; so this filter is unnecessarily restrictive. We therefore consider below the filtered 18 cases, plus 11 more that meet all the quality criteria except the age limits, leading to a total data set of 29 cases. 3 compares the preliminary statistical summary, listing mean and CoV Qc/Qm values of the API Main Text and CPT methods evaluated against the ICP, UWA, and the (29 cases, as described above) ZJU-ICL pile test data sets.
