The displacement pile is the oldest type of deep foundation and due to its proven efficiency is acknowledged and often employed in geotechnical engineering practice.
Although a lot of theories, methods and techniques were developed to predict and simulate the behaviour of displacement pile in cohesion-less soil (Baziar et al.
The 1st type of tests was aimed to reveal the shear and normal stresses distribution at displacement pile interface and the 2nd type of tests had to explain the origin of determined particular stresses distribution.
The existence of numerous displacement pile bearing capacity prediction methods and techniques (including the listed above) shows that no general and relevant method has been proposed so far.
The 1st type of tests aimed to reveal the shear and normal stresses distribution at displacement pile interface.
After 2 days the static vertical load test was performed and detailed short displacement pile response was obtained.
The performed static load tests of the short displacement pile determined, that the highest shear stresses on the pile skin get concentrated near the pile tip.
This means that the stress state is one of the governing criteria for describing the failure state of displacement pile.
Other topics include structural characteristics and the key technical design of wind turbine foundations in the Shanghai Donghai-Bridge Offshore Wind Farm, predicting pile setup and its resistance factors for southern Louisiana, the axial capacity of drilled shafts in clay over gravel formations, effects of cyclic frequency and pre-loading on the behavior of plate anchors, numerical simulations of a tube-installed displacement pile
in sand using the stress-controlled method, the strength and deformation of characteristics of lagoonal clay deposits in China's Lixia River area by seismic piezocone tests, and monitoring in situ soil moisture variation of expansive clay using neutron probes.
