Pile driving in low- to medium-density chalk is subject significant uncertainty. Predictions of “chalk resistance driving” (CRD) often vary considerably from field behaviour, with both pile refusals and free falls under zero load being reported. However, recent studies have led better understanding the processes that control wide range behaviour seen field. This paper describes primary outcomes...

The reliability of high-rise buildings’ rigid-pile composite foundations primarily relies on the load test results single-pile foundations. Field tests were conducted for a building in loess area China, conformed to design requirements. Nevertheless, buildings experienced significant settlement after construction, which was quite different from results. Investigating bearing disparities between...
