Parameter identification of soil-pile system by the dynamic testing method

Dynamic Pile Testing Technology: Validation and Implementation

Dynamic Interaction of Soil-Pile-Structure under Seismic Action

Due to randomness of seismic load, it is difficult to predict the complexity of the soil, pile, structures and their system. Presently, there isn’t a better way to explain and simulate the dynamic interaction of soil-pile-structure completely and precisely. Based on the stiffness expressions of interaction, the improved physical and mathematical models are setup to reflect the basic mass, stiff...

Dynamic and Static Properties of Pile- Soil Interface

The research progresses in static and dynamics tests, constitutive models, interface elements, model tests and field tests of pile soil interface are summarized, and the problems and deficiencies in the current research are analyzed. It is pointed out that research on the dynamic characteristics of pile soil interface widely seen in practical engineering are in lack. Especially, big size experi...

Parameter Estimation of Loranz Chaotic Dynamic System Using Bees Algorithm

An important problem in nonlinear science is the unknown parameters estimation in Loranz chaotic system. Clearly, the parameter estimation for chaotic systems is a multidimensional continuous optimization problem, where the optimization goal is to minimize mean squared errors (MSEs) between real and estimated responses for a number of given samples. The Bees algorithm (BA) is a new member of me...

Dynamic Pile-soil-pile Interaction. Part I: Analysis of Axial Vibration

Simple methods of analysis are developed for computing the dynamic steady-state axial response of floating pile groups embedded in homogeneous and non-homogeneous soil deposits. Physically-motivated approximations are introduced to account for the interaction between two individual piles. It is found that such an interaction arises chiefly from the ‘interference’ of wave fields originating alon...
