Scour around hydraulic structures is an inevitable phenomenon . Recognition of this phenomenon and dealing with it is an issue considering which will ensure the project success . Local scour at piers has been reported as the most important factor in the destruction of the bridges . The use of submerged and non-submerged piles is one of the scour control methods . Submerged piles have been rarel...

In tlie British Medical Journal, November 2Gth, 1898, Mr. Thelwall Thomas published an account of an operation for piles which I have tiied and found so satisfactory that I have since been in the habit of performing it on all my cases. The results are excellent, and it has the advantage of being easily and quickly performed. The patient complains of very little pain and recovery is rapid. A ful...

Energy piles are an effective and economic means of using geothermal energy resources for heating and cooling buildings, contributing to legislative requirements for renewable energy in new construction. While such piles have been used for around 25 years with no apparent detrimental effect, there is limited understanding of their thermo-mechanical behaviour. This paper synthesises the results ...

Despite widespread research effort in recent years, design methods to estimate the shaft resistance of displacement piles continue to rely heavily upon empirical correlations. In an attempt to achieve a more reliable design approach several researchers have assembled databases of instrumented pile load tests and used these to propose new design methods e.g. American Petroleum Institute (API-200...

Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...

An aerated static pile system with temperature feedback control was used for the composting of sewage sludge amended with olive tree leaves in a 1:1 (SS1) and 1:2 (SS2) v/v ratio, on two different occasions. The two piles were approximate 20 m3 each of similar dimensions; 2.0 wide at the base, 1.3 m height and 11 m long. Samples were taken from the core of the piles on four occasions: day 0 (es...

most codes such as api and bsi recommend morison’s equation to estimate hydrodynamic forces on offshore structures. significant differences exist among these codes due to using different methods of analysis and estimation of force coefficients. in this paper, data from full scale tests have been used to evaluate random waves and uniform current actions on the smooth piles. four time and frequen...
