Experiments on Reducing Negative Skin Friction of Piles [PDF]
The objective of this study was to investigate the effect of different moisture contents of clay (13%, 15%, 17%, 19%, and 21%) and different coatings on the ability to reduce negative skin friction during a large-scale shear test. Four coating treatments

The Group Effect on Negative Skin Friction on Piles [PDF]
AbstractWhen piles are constructed in consolidating ground, negative skin friction (NSF) is induced as a result of the downward movement of the soil relative to the pile. Model tests on negative skin friction on pile groups in sand were designed and conducted. Pile stress, pile top displacement and layered settlement of soil were tested under different

Study on negative skin friction of piles induced by mining subsidence using transparent soil model tests [PDF]
Due to surface subsidence caused by coal mining, the negative skin friction (NSF) has seriously threatened the safety of piled building foundations. In order to study the mechanism of the NSF of piles during the mining subsidence process, a set of pile ...

Behavior of Pile Subject to Negative Skin Friction and Axial Load
Centrifuge model tests have been conducted to investigate the effect of negative skin friction on piles installed through soft clay and founded in underlying dense sand. The first test series involved the study of fundamental mechanism of piles subject to negative skin friction only.

Numerical analysis of negative skin friction on piles in soft clay
Negative skin friction is considered one of the problems in the design of piled foundations in soft soil. The negative skin friction induces an additional compressive force on the pile called the dragload as well as, an additional pile movement called ...
