Abstract

Giant Sea Wall Jakarta merupakan tanggul penahan yang dibangun di teluk Jakarta untuk melindungi wilayah utara pesisir dari erosi dan pasang-surut air laut yang menyebabkan banjir rob. Selain itu, Giant Sea Wall Jakarta juga berfungsi sebagai dinding penahan tanah reklamasi. Strukturnya berbentuk sheet pile. Dari data perencanaan Giant Sea Wall Jakarta oleh PT. WIKA Beton, ditemukan bahwa pembebanan yang direncanakan hanya akibat beban statis yaitu beban tambahan sebesar 15 kN/m2 di atas tanah reklamasi. Struktur tidak direncanakan terhadap beban dinamis yaitu kemungkinan terjadinya gempa. Struktur ini akan dijadikan sebagai preliminary desain. Struktur akan didesain secara elastis. Dari hasil analisa yang telah dilakukan, didapatkan kesimpulan bahwa momen terbesar ialah akibat beban dinamis dengan cara analitis yaitu 2391,7 kNm/m dengan panjang cylinder pile 24 m dan diameter 1,2 m. Pada analisa penampang didapatkan tegangan pratekan saat peralihan -18,29 MPa. Setelah dihitung momen crack penampangnya, didapat lebih besar dari momen yang terjadi yaitu sebesar 2784,5 kNm/m. Sehingga preliminary desain sebelumnya dapat digunakan untuk struktur Giant Sea Wall Jakarta. ============================================================================================ Giant Sea Wall Jakarta is a retaining embankment built in the bay of Jakarta to protect the northern coastal areas from erosion and tidal seawater causing rob floods. In addition, Giant SeaWall Jakarta also serves as a retaining wall of reclaimed land. The structure’s form is sheet pile. From the data planning of Giant SeaWall Jakarta by PT.WIKA Beton,it was found that the planned loading was only due to the static load which was an additional load of 15 kN/m2 on the reclaimed soil. Unplanned structure to dynamic load is the possibility of an earthquake. This structure will serve as a preliminary design. The structure will be elastically designed. From the results of the analys is that has been done, it can be concluded that the biggest moment is due to dynamic load with an analytical way that is 2391,7 kNm/m with 24 m long cylinder pile and 1.2 m in diameter. In the cross-sectional analysis, a prestressing is obtained at -18.29 MPa. After calculated crack moment of cross section, got bigger than moment that happened that is equal to 2784,5 kNm/m. So the previous preliminary design can be used for the structure of Giant Sea Wall Jakarta.
