Abstract

ABSTRACT Energy dampers are part of the weir that serves to dampen the energy of the water flow through the weir. Most of the dam damages in Indonesia are caused by the local scouring that occurs continuously downstream of the weir. The local scour is caused by considerable potential energy due to the differences in water level upstream and downstream of the weir. Local scours occurring downstream of the weirs caused by high water levels from damming, endanger the construction of the weir itself. To prevent deep scouring of long energy dampers, a new energy damper is planned. The main factor of the deep scouring on the downstream of the dam is the energy damper that has not functioned optimally. In this research used damper type energy sink. In the design of energy damper, based on flood water level +108,884 m, elevation of weir of +108,244 m, height of 2.5 m and flow rate 2,4217 m / sec found the condition of super critical flow during flood water and for dimension of energy damper: 8.25 m hydraulic jumping length, 1.86 m wake length, 2.75 m tube fingers and 2.35 m foundation depth. From the stable stability analysis of the dam to the bolsters, shear, the carrying capacity of the soil and the building does not decrease due to the load or soil stress that occurs. Keywords ; dams ; energy dampers ; hydraulic analysis ; stability.

Abstract

ABSTRAK Aspek hidraulik pada bendung merupakan salah satu faktor yang penting dalam perencanaan Peredam Energi (Stilling Basin) air yang jatuh, sehingga sisa energi air di hilir kolam olak menjadi minimal sehingga gerusan dasar sungai tidak membahayakan. Yang jadi masalah adalah kedalaman gerusan hilir bendung seberapa jauh membahayakan sehingga perlu dilakukan analisis dengan tujuan untuk mengetahui profil bendung Eksisting dan peredam energi yang mana lebih stabil, mendapatkan hasil Lj + Ld yang diperlukan untuk bendung yang akan direncanakan kembali, mengetahui evaluasi panjang kolam olak Lj + Ld terhadap existing dan stabilitas. Evaluasi dilakukan dengan menghitung debit rencana pada kolam (Q), kecepatanaliran air pada kedalaman kritis (Vz), kedalaman kritis (Yz), dan bilangan Froude (Fr). Dari hasil perhitungan, diperoleh debit rencana sebesar 7,356 m3/dt, kecepatanaliran air pada kedalaman kritis sebesar 3,2827 m/dt, kedalaman kritis sebesar 0,153 m dan bilangan froude 6,522. Hasil perhitungan ini merupakan hasil dari perencanaan peredam energi. Artinya kasil evaluasi yang dilakukan mengharuskan kolam olak perlu dilakukan perencanaan baru untuk mengantisipasi gerusan. Dari hasil perhitungan dan analisis diperoleh nilai Fr pada profil bendung adalah 6,25 berada di bawah hilir bendung, panjang loncatan hidrolis adalah 14 m dan panjang kolam olak 7 m.

Abstract

Land is an important aspect in the planning of construction. Because the land has the standing of a building. Therefore, it is important to take into account the stability of the soil. One of the ways used to control the stability of the ground so as nor to experience sliding is to build a retaining wall. Planning retaining wall is located on the Weybolar River, West Southeast Maluku District and located on seismic zone 5. On this plan, the data used comes from the Public Works Department of Mining and Energy, West Southeast Maluku District. The planned retaining wall is a kind of gravity. So this building can function properly, then the stability of the building should also be good. Therefore, the author tries to analyze the stability of the retaining wall against the danger of rolling and sliding with normal water level condition without the earthquake, with the earthquake and flood water level condition without the earthquake, and with earthquake. Analyze using the Rankine formula. The result is SFsliding 1,77 > 1,5 and 1,38 > 1,2, SFbolters 2,5 > 1,5 and 1,2 ≥ 1,2 (for normal condition without and with the earthquake) and SFsliding 1,93 > 1,5 and 1,38 > 1,2, SFbolters 2,97 > 1,5 and 1,56 > 1,2 (for flood condition without and with the earthquake), it turns out safely.
