We present exact results for the contact forces in a three dimensional static piling of identical, sti and frictionless spheres. The pile studied is a pyramid of equilateral triangular base (“stack of cannonballs”) with a FCC (face centered cubic) structure. We show in particular that, as for the two dimensional case, the pressure on the base of such a pile is uniform. c © 1999 Elsevier Science...

in this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. the bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. a total number of one hundred and two (102) sensors are...

Rock-socketed pile is widely used in coastal wharf, Marine bridge, and power engineering, the end bearing function considered more design process. However, lateral friction resistance of rock-socketed piles an important part, load transfer mechanism pile–soft rock interface research focus. In this paper, a comparative analysis was adopted test, ten groups test specimens were made, including fiv...

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 settlement of a group pile foundation is the result elastic-plastic and rheological soil. Unfortunately, most research only considers elasto-plasticity piles or soils. Classical theories like Poynting-Thompson model provide some prediction for behavior groups, which cannot satisfactorily reflect total characteristics foundation. In current paper, we presented method to study behaviors in li...

This study evaluated the lateral and overturning resistance of wind turbine foundations reinforced with piles on bedrock through model experiments. In particular, changes in were analyzed according to cross-sectional size presence foundations. As a result, by reducing cross-section, pile-reinforced foundation was compared existing large cross-sections shown be 1.68 times greater. case vertical ...
