Scour features of sea-crossing bridge piers
Shuili Shuiyun Gongcheng Xuebao, 2021 The local scour around bridge piers is one of the main safety influence factors of sea-crossing bridges in the nearshore region. Based on the survey data of six bridge piers of Jintang Sea-Crossing Bridge in Hangzhou Bay during 2014, 2015 and 2017, the ...

Lane’s Relation in Local Scour Investigations [PDF]
IEEE Access, 2020 Alluvial river channels undergo transformations due to fluvial processes such as water flow which invokes soil particles movement. Mentioned processes are interrelated and can be described as a feedback relation which means that hydraulic and morphological features adjust to each other during the process of obtaining the dynamic balance between water ...

Effect of Porosity on Local Scour Around Circular Array of Cylinders in Steady Currents
Shanghai Jiaotong Daxue xuebao, 2022 The local scour around a circular array of cylindrical piles through physical model was studied under the live-bed condition, concerning the effect of porosity of the structure on the local scour development.

Local Scour Mechanism of Offshore Wind Power Pile Foundation Based on CFD-DEM
Journal of Marine Science and Engineering, 2022 The local scour around offshore pile foundations often seriously affects the normal operation of offshore wind power. The most widely used numerical simulation method in the study of local scour is the Euler two-fluid model (TFM).

Large-scale experimental study on scour around offshore wind monopiles under irregular waves
Water Science and Engineering, 2022 The Keulegan-Carpenter (KC) number is the main dimensionless parameter that affects the local scour of offshore wind power monopile foundations. This study conducted large-scale (1:13) physical model tests to study the local scour shape, equilibrium ...

Experimental study on local scour depth around pile groups
Energy Reports, 2022 An accurate prediction of local scour depth at piles is essential for bridge safety. In order to obtain the prediction formula of local scour around pile groups, a series of local scour experiments of pile groups were carried out.

On Local Scouring at Single Piers
Scientific Research Communications, 2021 The paper mostly summarizes disperse contributions of the authors published during the last fifteen years on the scour depth at single piers. These contributions rely on unique experiments in the sense that they are systematically longer than most of those found in the literature.

Checking the Accuracy of Selected Formulae for both Clear Water and Live Bed Bridge Scour
Journal of Engineering, 2023 Due to severe scouring, many bridges failed worldwide. Therefore, the safety of the existing bridge (after contrition) mainly depends on the continuous monitoring of local scour at the substructure.
