MODEL PENURUNAN SEDIMEN PERMUKAAN DASAR LAUT PADA DASAR RENCANA PEMECAH GELOMBANG DI TELUK PANCAMAYABANYUWANGI - JAWA TIMUR
Abstract
Demi menghasilkan pemecah gelombang yang aman, maka perlu dilakukan analisis geologi dan geoteknik kelautan. Analisis ini akan memberikan informasi tentang kondisi fisik sedimen laut yang mengalami suatu perubahan pembebanan akibat adanya infrastruktur kelautan. Berdasarkan hasil analisis Plaxis versi 8, maka dapat diketahui bahwa besarnya nilai total deformasi yang disebabkan oleh beban struktur setinggi 8 meter dan gaya arus sebesar 1 kN/m2 adalah sebesar 72,77*10-3 m. Lapis sedimen sekitar badan dan kaki pemecah gelombang memiliki nilai deformasi ekstrem yang lebih merata sedangkan nilai ekstrem deformasi terjadi pada tengah struktur di kedalaman -5,50 meter.

Marine geology and geotechnical analyses are indeed important in order to get a safe breakwater design. To build a safe infrastructure, these analyses would produce a model to describe the displacement condition of marine sedimen. Applying 8 meters height of breakwater and 1 kN/m2 current, the Plaxis software v.8 gave a result 72,77*10-3 m of total deformation. In addition, an extreme deformation occurred in the middle of -5,50 meters breakwater, while equilibrium deformation occurred around areas between toe and breakwater body.
