The ultimate capacity of a novel type piled foundation called an ‘impression’ pile has been investigated using centrifuge modelling techniques. name derives from the small discrete impressions created in side walls bored cast situ to increase soil/pile friction such that form nodules on shaft concreted pile. technology is suitable for piles overconsolidated clay, as London Clay. experiments exp...

Using a series of model tests, this study investigated the effect of a passive pile on 3D ground deformation around a laterally loaded pile and on that laterally loaded pile's response in sand. The active pile head was subjected to lateral loads, and the passive pile was arranged in front of the active pile. In the model tests, the distance between the two pile centers was set to zero (i.e., a ...

Vibratory installation of piles and casings can be extremely economical and therefore the contractors’ preferred method of pile driving. Compared to impact pile driving it also has the advantage of reduced noise pollution. Unfortunately, this installation method is still fraught with uncertainties. The foremost question is driveability and equally important is the question of bearing capacity o...

The thermo-mechanical behaviour of concrete energy pile foundations with different single and double U-tube shapes incorporated was analysed using the Comsol Multi-physics package. For the analysis, a 3D numerical model in real scale of the concrete pile and surrounding soil was simulated regarding actual operation of ground heat exchangers (GHE) and the surrounding ambient temperature. Based o...

Compared with conventional piles such as the circle pile, the cast-in-place large-diameter pile (PCC pile) has many advantages: the lateral area of PCC pile is larger and the bearing capacity of PCC pile is higher. It is more cost-effective than other piles such as square pile under the same condition. The deformation of the PCC pile is very important for its application. In order to obtain the...

alcohol production from molasses can lead to large amounts of wastewater that cause serious environmental concern. it is characterized with extremely high organic loading rate, high turbidity and dark brown color .composting this kind of wastewater is a biothermal aerobic process that during composting heat generated by the composition of the organic material reduces the moisture content of the...

The use of static load testing in optimising design and providing verification of suitability and constructability continues to be unsurpassed in the foundation industry. The utilisation of top load reaction testing appears to be that with which most European engineers are familiar, but a variation on this, which has become just as conventional in some parts of the world, is the use of bi-direc...

Considering viscoelastic saturated soil, The transient dynamic response of an elastic pile is studied. The pile-soil system is divided into thin layers, the control equations of the soil are solved respectively by using Laplace transform. Considering the mixed boundary-value conditions at the interface of pile and soil, expression is derived to describe the relationship between the inner force ...

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...

The article substantiates the need for this study, analyzes advantages and disadvantages of various working bodies loading devices, as well results analysis on prospects a finger-type separating body uniform pile seeds into dryers. factors influencing process leveling material methodology experimental research are given. maximum number under study has been determined, most likely areas their ch...
