Abstract

Pada tugas akhir ini memakai 3 desain bendungan antara lain desain eksisting, desain alternatif I, dan desain alternatif II. Pada semua desain tersebut ditentukan permodelan MAB +194.61, MAN +192.1 dengan adanya Deadstorage setinggi +134.5, dan Surut Cepat dari kondisi MAN sampai Mercu Intake +175.0. Semua desain bendungan dengan permodelannya dilakukan analisis menggunakan program bantu Geo-Studio 2012 antara lain analisis rembesan, dan analisis stabilitas. Pada analisis rembesan akan mendapatkan hasil berupa pola rembesan, kecepatan rembesan, debit rembesan. Sedangkan hasil dari analisis stabilitas akan mendapatkan angka keamanan pada lereng hulu dan hilir yang mana angka tersebut mengacu pada SNI 2016. Desain alternatif II merupakan desain yang memiliki hasil lebih efektif dibanding dengan desain yang lain. Pada hasil analisis rembesan desain alternatif II memiliki kecepatan, debit rembesan yang paling kecil dibanding dengan semua permodelan (MAB = 9.14 x 10-7 m/s ; 6.46 x 10-11 m3/det, MAN dengan Deadstorage = 6.90 x 10-7 m/s ; 6.12 x 10-11 m3/det, dan Surut Cepat = 4.49 x 10-5 m/s ; 6.11 x 10-11 m3/det). Sedangkan pada hasil analisis stabilitas desain alternatif II memiliki SF lebih dari 2 pada tiap permodelannya dan dapat dikatakan aman karena pada acuan SNI 2016 menjelaskan bahwa pada kondisi permodelan MAB dan MAN dengan Deadstorage memiliki SF 1.5 serta Surut Cepat memiliki SF 1.3. Kata Kunci: Tubuh Bendungan, Material, Analisis Rembesan, Analisis Stabilitas, Efektifitas ================================================================================================= In this final project use 3 dam design among others the existing design, alternative design I, and alternative design II. In all of these designs the model was determined MAB +194.61, MAN +192.1 with Deadstorage +134.5, dan Receded Quickly from conditions MAN until Mercu Intake +175.0. All dam designs with modeling were analyzed using Geo-Studio 2012 program, among others seepage analysis, and stability analysis. In seepage analysis will get the result of seepage pattern, seepage velocity, seepage discharge. While the results of the stability analysis will get a safety factor on the upstream and downstream slopes in which the figure refers to SNI 2016. Alternative design II is a design that has more effective results compared with other designs. In the result of seepage analysis of alternative design II has seepage velocity, and smaller seepage discharge compared with all modeling (MAB = 9.14 x 10-7 m/s ; 6.46 x 10-11 m3/det, MAN with Deadstorage = 6.90 x 10-7 m/s ; 6.12 x 10-11 m3/det, dan Receded Quickly = 4.49 x 10-5 m/s ; 6.11 x 10-11 m3/det). While on the result of stability analysis of alternative design II has SF more than 2 on each modeling and can be said safe because in reference to SNI 2016 explains that at condition of modeling of Flood Water Level and Normal Water Level with Deadstorage have SF 1.5 and Receded Quickly have SF 1.3.
