... Abstract The paper presents an experimental study of local scour around truncated vertical piles subject to oscillatory flow. The experiments were conducted with six height-to-diameter ratios ( h/D =0.25~3.5) and three KC numbers (33, 52 and 80). The development of scour depth around...

... ABSTRACT Landing pier, which has been one of the most important harbor facilities, generally employs the combination of vertical piles and batter piles for foundation. In the design of landing piers, the lateral loadings due to earthquake as well as wave actions should be considered. Despite...

... with vertical piles in groups. The behaviour of piles under either axial compression or uplift force has been well understood and various methods are available to predict the behaviour of vertical and batter piles subjected to pure axial loads. However, there are some field situations in which batter piles...

... load acts opposite to the direction of the pile inclination(Fig.1). Many theoretical and experimental studies were carried out by several investigators on laterally loaded vertical piles in clays to determine their ultimate resistance and several criteria were proposed to predict load-deflection...

... ABSTRACT The time scale of the scour process around a single, vertical pile is studied both in steady current and in waves. An extensive series of tests were carried out in a current flume and in a wave flume with various sizes of circular cross-section piles ranging from 30 mm to 510 mm...

... ABSTRACT The in-line and lift forces on vertical piles in side by side arrangement induced by both irregular waves and currents were investigated experimentally in this paper. The characteristics in both time and frequency domain of in-line, lift and resultant forces as well were analyzed...
