This paper presents the influence of non-linearity on the dynamic response of floating pile foundation subject to vertical vibration. A detailed theoretical investigation of stiffness and damping parameters is made for floating piles with different shear modulus reduction ratio of the weak zone soil. The accuracy of the non-linear analysis for predicting the dynamic response depends upon the ch...

The principal objective of this thesis is to assess the capabilities of an already established analytical framework for understanding and predicting the behavior of piles driven in highly overconsolidated clays (OCR24). The skin friction mobilized during pile loading to failure depends on the sequence of preceding events, i.e. pile installation and soil consolidation. This research utilizes the...

In order to study the deformation of a bored pile during concrete curing, it is necessary monitor strain pile. this paper, Brillouin optical time domain reflectometer (BOTDR) technology used and reliable monitoring data are obtained. These provide basis for pile–soil interaction curing cast-in-place piles. Compared with traditional point sensor, distributed fiber optic sensor simple in layout h...

A mathematical model for an outer soil, multi-defects pipe pile, and inner soil dynamic interaction system is established to research the influences of on vibration a pile. The impedance pile deduced by applying Laplace transformation method recursive technique. Then, velocity response at head further obtained using inverse Fourier transform method. Moreover, parametric analyses are conducted t...
