In calcareous sand, when the pile tip resistance increases to a certain extent, particle breakage occurs and the stresses in the soil cannot continually increase. Therefore, the pile tip resistance fluctuates around a stable value (0.3MPa). This is the reason that the pile tip resistance in ...
Model tests of a single pile bearing vertical cyclic loads were performed in calcareous sand, and the accumulated settlement and bearing capacity were measured via sensors using a self-designed experimental device. The influences of the dynamic load and number of cycles on the accumulated settlement ...

[49]. All ingredients were well blended and then composted in a pile measuring 25 × 2 × 1.6 m (length x width x height). The pile was turned over four times a month during the bio-oxidation stage and regularly sprinkled with water to maintain a 60% (v/w) wet level. ...
The effect of breakable particle corners is often overlooked in research on pile–soil interaction, which hinders the understanding of the uplift pile
Particle breakage is a key attribute of calcareous sand. Given that foundations on calcareous sand islands encounter various types of loads, including pile driving, aircraft loading, earthquakes, and tsunamis, it is imperative to investigate its mechanical properties and particle breakage under high ...
The mechanical response and deformation characteristics in calcareous sand foundations during pile driving and setup were studied using model tests combined with the technical methods of tactile pressure sensors and close-range photogrammetry. Different types of piles were considered, including a pipe pile...
