Foundation piles have the potential to improve economic and technical feasibility of ground source heat pump (GSHP) systems. They simultaneously provide structural support energy for space heating cooling. In this study, a thoroughly verified validated numerical model novel in-ground exchanger GSHP systems is developed used simulate optimize performance. Commercially available helical steel cas...

impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. at first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. this is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. it is of high ...

numerous techniques have been presented by different researchers to analyze piled raft. in order to analyze pile foundation, soil can be modeled as spring, continuous medium, or porous media. pile can also be modeled as spring or continuous medium. this study includes three main stages: a short description of different types of analysis methods of pile foundation, writing a computer program bas...

It is very difficult to predict the load carrying capacity of bored piles because of the Complications that may arise such as difficult ground conditions , presence of ground water, method of boring, method of concreting, quality of concrete, expertise of the construction staff, the ground conditions and the pile geometry. Therefore the Pile design must be accompanied by in situ load testing. M...

The article presents the thermal technical calculation of underground heat accumulator, which is used to prevent a sharp increase in air temperature hothouses on sunny days and accumulate solar energy. coefficient transfer by air-pipe pipe-soil boundary layers between 20-35 °C air-driven accumulator with help ventilator was calculated analytical method. mathematical model change time length dur...
