Abstract

The need of dam is considered necessary for an area, the residential area located in the Watershed (DAS) experience frequent flooding when the river water is at high water level. That is why we need to learn the behavior of the soil embankment dams associated with the stress-strain, pore water pressure and stability to obtain a soil embankment dam design is safe from collapse or failure. Various ways can be done to analyze it, one of which program is to make a model dam with a calculation using the program Plaxis. In modeling this dam soil was taken from the site Doloduo II, Kotamobagu, namely silty clay then modeled in an experimental box. Dams were given treatment in the form of the addition of water to a certain height. Dam stability is observed with pore water pressure and other things that happened in the modeling, then compared with analysis using Plaxis 3D Foundation program is made in three calculation process. Keyword: Modeling of dam, Stress-Strain, Pore Water Pressure, Program Plaxis.

Abstract

Soil Nailing dan Anchor merupakan konstruksi yang masih terbilang jarang digunakan di Sulawesi Utara. Penelitian ini mengkaji akan kebutuhan konstruksi tersebut ditinjau dari segi kekuatan dan penggunaan lahan untuk konstruksi. Dengan mengambil sampel tanah dari salah satu titik longsor yang terjadi pada 15 Januari 2014 kala itu juga banjir bandang melanda Kota Manado, kemudian data tanah tersebut di masukkan ke dalam program Plaxis 2D yang dianalisis berdasarkan Finite Element Method dengan data profil potongan melintang kemiringan lereng sesuai kondisi lapangan. Hasil penelitian ini menunjukkan bahwa solusi ini dianggap tepat dan mampu menahan tanah dari kemungkinan longsor meski pada kondisi tanah jenuh air sepenuhnya. Kata Kunci : Soil Nailing, Anchor, Plaxis 2D, Finite Element Method
