Scour Below Submerged Skewed Pipeline
Hakisan dibawah saluran paip terjadi disebabkan oleh tindakan arus sungai yang menyebabkan saluran paip terdedah kegagalan. Saluran paip merentasi sungai menganggu aliran sungai dan seterusnya menyebabkan kesan aluran yang bertindak balas dengan pusaran air di sekitar saluran paip. Dalam penyelid...

| description | Hakisan dibawah saluran paip terjadi disebabkan oleh tindakan arus sungai yang menyebabkan
saluran paip terdedah kegagalan. Saluran paip merentasi sungai menganggu aliran sungai dan
seterusnya menyebabkan kesan aluran yang bertindak balas dengan pusaran air di sekitar saluran
paip. Dalam penyelidikan ini, beberapa ekspresimen dijalankan untuk mengkaji dari segi fizikal
kesan pemasangan saluran yang dipesongkan mengikut darjah (30º, 45º, 60º dan 90º) merentasi
sungai. Penyelidikan ini juga bertujuan untuk menilai GEP dan model-model regrasi sebagai
salah satu medium dalam menentukan hakisan di bawah saluran paip yang dipesongkan
merentasi sungai. Permulaan proses hakisan bagi kedalaman air (y/D =3) meningkat dengan
mendadak. Walau bagaimanapun, bagi y/D = 4, permulaan proses hakisan adalah lebih perlahan.
Local scour below submerged pipelines occurs due to the erosive and action of currents which
cause pipeline failure. The presence of pipe across river initiates the piping effect combined with
the stagnation eddy and vortex system undermine the pipeline and mark the onset of scour. The
main objective of the research is to investigate the physics of scour below pipeline in river
crossing as well as its factor associated. In this study, experiments were conducted to investigate
the effect of four different pipeline angles (30º, 45º, 60º and 90º) across a channel. |
