Laboratory measurements were undertaken to investigate wave and current velocities in the vicinity of a wind turbine monopile foundation, in order to inform environmental impact assessments and to quantify flow variability in the region of the power take off cable. Flow measurements were made up to 15.5 pile diameters (D) downstream of the pile. Measurements were also taken around the perimeter...

The bonding state of the pile-soil interaction is complex. Traditional monitoring methods and tools have not been fully applied to monitor evaluate it although affects lifecycle safety pile. In this study, a health method proposed contact area; transient impact response based on piezoelectric ceramic sensors state. During test, different damage degrees were simulated by considering working cond...

Several authors have written papers dealing with a class of combinatorial games consisting of one-pile and two-pile counter pickup games for which the maximum number of counters that can be removed on each move changes during the play of the game. See Holshouser [8],[7], and Flanigan [4]. The maximum number of counters that can be removed can depend upon a number of factors including the number...

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...

The integrity of cast-in-place foundation piles is a major concern in geotechnical engineering. In this study, distributed fibre optic sensing (DFOS) cables, embedded in a pile during concreting, are used to measure the changes in concrete curing temperature profile to infer concrete cover thickness through modelling of heat transfer processes within the concrete and adjacent ground. A field tr...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

This research is to assess the influences of inertial mass from girder on dynamic characteristic, response, and structure-soil interaction a pile-soil-pier subsystem in scale-model cable-stayed bridge. Therefore, both connection configurations between girder, including sliding fixed connections, were designed present various superstructure delivered pile-soil-pier. The supported by 3 × pile-gro...

stable pile depth in the Snowy River study (SKM 2005) is outlined. The inputs used in the run of the LLP99 model were: • single soil layer, • very high flexural stiffness of pile (1,000,000 kN/m). • pile width = 0.3 m (i.e. wooden pile), • shear strength in the absence of lateral stress (for unconsolidated sand 150 kN/m was used), • effective unit weight of soil (15 kN/m), • active lateral effe...
