Sheet Pile

Wilayah hulu DAS Pekalen mengalami perubahan tata guna lahan yang menyebabkan terjadinya sedimentasi pada Kali Pekalen. Dengan adanya sedimentasi tersebut, maka dapat mengakibatkan berkurangnya kemampuan eksisting sungai untuk menampung debit, sehingga menyebabkan masalah banjir di sekitar wilayah Kali Pekalen. Dalam hal ini maka dilakukan analisa kapasitas Kali Pekalen dengan menggunakan aplikasi HEC-RAS untuk mengetahui kemampuan eksisting sungai dan juga mengetahui alternatif penyelesaian dari masalah banjir tersebut. Untuk melakukan analisa tersebut diperlukan analisa hidrologi untuk mendapatkan debit banjir rancangan. Metode yang digunakan untuk mencari debit banjir rancangan yaitu dengan menggunakan Hidrograf Satuan Sintetis Nakayasu dengan kala ulang Q50 th untuk wilayah hulu, tengah, dan hilir Kali Pekalen. Setelah mendapatkan hasil perhitungan debit banjir rancangan, maka dilakukan analisa aliran dengan menggunakan aplikasi HEC-RAS 5.0.7. Berdasarkan hasil analisa yang telah dilakukan, terdapat 163 ruas patok di wilayah hulu, tengah dan hilir Kali Pekalen yang tidak mampu menampung debit. Sehingga ada 163 ruas patok di Kali pekalen yang dipasang tanggul dengan desain Concrete Sheet Pile (CCSP) yang memiliki panjang 12 m, dan kedalaman 6,45 m dari dasar sungai.

Sheet Pile Wall

Recently, the limit states approach using factored strength has been recommended in geotechnical design. Some recent research has indicated that the application of limit states design using recommended load and strength factors leads to conservative designs compared with the conventional methods. In this study the influence of sheet pile wall geometry, type of water pressure distribution, and different methods of analysis on the maximum bending moment and achor rod force are presented. Recommendations are made to make the factored strength design compatible with conventional design. Key words: factored strength, working stress design, ultimate limit state design, anchored sheet pile wall, bending moment, anchor rod force.

Sheet Pile Wall

The construction of an underpass in the City of Edmonton required the temporary relocation of the CNR main-line prior to the construction of a permanent bridge. The line was placed close to the underpass excavation which was supported by a tie-back sheet pile wall. Because of the stringent requirements associated with the presence of the railway line, the supports were designed on a conservative basis and observations of tie-back loads were taken over a period of 7 months.This note presents the observations of tie-back loads from January to July, 1977. Following installation in accordance with the design requirements, substantial fluctuations in tie-back load were observed for about 3 months. Then the loads fell off gradually to about 50% of the originally applied values. The variation of the load with time bears a strong correlation with average air temperature and is accounted for by the alternate freezing and thawing of the ground adjacent to the sheet pile wall. The ultimate decline in load is attributed to relaxation of the soil behind the wall during spring thaw. The case history draws attention to special requirements associated with interpretation of earth pressure measurements during winter con struction.
