Temperature response functions (G-functions) for single pile heat exchangers [PDF]
, 2013 Foundation piles used as heat exchangers as part of a ground energy system have the potential to reduce energy use and carbon dioxide emissions from new buildings. However, current design approaches for pile heat exchangers are based on methods developed

G-Functions for multiple interacting pile heat exchangers [PDF]
, 2014 Pile heat exchangers – where heat transfer pipes are cast into the building piled foundations – offer an opportunity to use ground energy systems without the additional construction costs related to the provision of special purpose heat exchangers ...

Pile Head Cyclic Lateral Loading of Single Pile [PDF]
Geotechnical and Geological Engineering, 2014 This paper presents an elastic continuum model using an extended nonlinear Davies and Budhu equations, which enables the nonlinear behavior of the soil around the long elastic pile to be modeled using a simple expression of pile-head stiffness method. The calculated results were validated with the measured full-scale dynamic field tests data conducted ...

Behavior of single pile and pile groups in consolidating clay
IOP Conference Series: Materials Science and Engineering, 2020 Abstract As the pile group is commonly in use but the effect of consolidation times on the distribution of negative skin friction and drag force along the shaft of each pile in pile groups is still not well defined and studied. This paper presents the three-dimensional (3D) numerical analysis to study the behavior of a single pile and ...

The thermal behaviour of three different auger pressure grouted piles used as heat exchangers [PDF]
, 2014 Three auger pressure grouted (APG) test piles were constructed at a site in Richmond, Texas. The piles were each equipped with two U-loops of heat transfer pipes so that they could function as pile heat exchangers.

Field tests on bearing capacities of CFG pile and root pile
Yantu gongcheng xuebao, 2022 For the soft soil foundation slipped in the storage yard of a wharf, the composite foundations with CFG pile and root pile net are used for reinforcement in different zones. The field static load tests are carried out to study the bearing behavior of the

Use of Pile Driving Analysis for Assessment of Axial Load Capacity of Piles [PDF]
, 2012 Driven piles are commonly used in foundation engineering. Pile driving formulae, which directly relate the pile set per blow to the capacity of the pile, are commonly used to decide whether an installed pile will have the designed capacity.
