In recent years, there has been a significant push to develop optimized pile designs in the offshore industry, driven by growth of wind. One largest remaining uncertainties governing axial design sands is influence ageing effects and how an aged responds under cyclic loading. This paper presents results from long-term campaign field tests on loading sands, undertaken at Blessington geotechnical...

This finite-difference time domain (FDTD) model for sound propagation in very shallow water uses pressure and velocity grids with both 3-dimensional Cartesian and 2-dimensional cylindrical implementations. Parameters, including water and sediment properties, can vary in each dimension. Steady-state and transient signals from discrete and distributed sources, such as the surface of a vibrating p...

Concrete piles that were poorly constructed or analyzed in their soil analyses may have structural geotechnical defects. To examine such defects, an experimental study was conducted to investigate how a defective reinforced concrete pile behaved. These installed and subjected compression axial load the sand had relative densities of 30%,60%, 80%. The tests performed using four model piles: one ...

ABSTRAKRencana pembangunan pembangkit listrik tenaga surya di bali. Karena berada lokasi bukit tinggi dekat laut yang dimana memiliki hembusan angin cukup kuat sehingga memengaruhi aksial tekan dan tarik. Oleh karena itu alternatif untuk menahan beban tarik yaitu menggunakan fondasi Helical pile penempatanya bebatuan tanah Limestone. Dalam pemodelan helical divariasikan spasi helix nya 0,1 m; 0...
