The relationship between production and reef pile size was analysed using standing stocks of fishes surveyed at three established artificial reef (AR) habitats in the subtropical waters off the northern coast of Taiwan during April–August 1999. For a closer look, the fish assemblage was further divided into visitors and residents, and biomass was used as a parameter to represent production. Vis...

This paper describes the development of an accurate long-distance position measurement system for construction pile using Laser Range Finders (LRF). The pile positioning and driving is the first work that is one of the important works to request the attentions in the building construction. In general, though the position of piling is measured by the total station that is high accurate survey ma...

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Pile heat exchangers – where heat transfer pipes are cast into the building piled foundations – offer an opportunity to use ground energy systems without the additional construction costs related to the provision of special purpose heat exchangers. However, analysis methods for pile heat exchangers are still under development. In particular there is an absence of available methods and guidance ...

The problem of soil±pile±foundation±superstructure interaction is examined, and a simple rational procedure to analyse the response of a structure supported on pile groups is presented. This procedure combines theories for the computation of the dynamic impedances and kinematic±seismic response factors of pile foundations with a multi-degree-of-freedom structural model. The procedure is applied...

We consider a modified Bouchaud-Cates-Ravi Prakash-Edwards model for pile surface dynamics, and show that in the long-scale limit this model converges to a quasistationary model of pile growth in the form of an evolutionary variational inequality.

The wind turbine foundation serves as a permanent construction in the harsh marine corrosive environment, its anticorrosion design is essential to the safe use of the wind turbine structure. At present, there is a significant controversy over the local corrosion mechanism (such as pitting corrosion, and crevice corrosion) and its diffusion mechanism in the academic circle. In the paper, the Far...

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...
