The characteristics of bridge pile-group foundation have a significant influence on the dynamic performance superstructure. Most existing analysis methods for impedance take trait strong specialty, which cannot be generalized in practical projects. Therefore, project-oriented numerical solution algorithm is proposed to compute foundation. Based theory viscous-spring artificial boundary, derivat...

Extensive numerical and analytical studies exist that focus on the scours around bridge piers with different cross-sections. However, addressing scour piles are rather limited not conclusive. Therefore, most efficient cross-section reducing local a pile group is experimentally examined herein. Accordingly, comparative scouring of three shapes, namely, circular, rectangular lenticular, investiga...

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...

Grouped and single pile behavior differs owing to the impacts of the pile-to-pile interaction. Ultimate lateral resistance and lateral subgrade modulus within a pile group are known as the key parameters in the soil-pile interaction phenomenon. In this study, a series of experimental investigation was carried out on single and group pile subjected to monotonic lateral loadings. Experimental inv...

This paper summarizes results of a major study on jointless bridges sponsored by the U.S. Federal Highway Administration. This study included extensive laboratory and field experiments as well as detailed analytical studies. A set of design recommendations were provided. Jointless bridges have reduced maintenance, improved riding quality, lower impact loads, reduced snowplow damage, and structu...

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...

This paper reviews the summary and analysis of special technical safety schemes for hazardous ultrahazardous activities, supported by housing scaffolding, installation, dismantling outer wall attached tower crane, deep foundation pit with supporting structure, municipal bridge box girder formwork support, as well grooved Larsen steel sheet pile, which are commonly seen in recent years, so to en...

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...
