Pengaruh Pembuatan Terasering Pada Lereng Terhadap Potensi Longsor
Abstract: Indonesia is one
country with the population growth rate is large. This condition will require
the opening of new land for settlement. Limited land sometimes requires people
to open new land on the slope areas. Opening of new land on the slopes will use
the method of cutting the slope to get flat land (terrace). Cutting this slope
would result in increased potential for landslides due to slope stability
menurunya. Evaluation needs to be done at the opening of new land on the
slopes, where the slope should remain stable after the porch is made. This
research was conducted to evaluate the maximum terrace width was in stable
condition. The model used in this study is a plane strain by the count to
element method. The main purpose of this research is to obtain the maximum
terrace width formula on a slope. Dilakukan analysis on three ).�), cohesion, (c) and angle of
internal friction (�variables,
namely slope( Variations to the variable angle between 30o-55o intervals 5o, 5
kN/m2 cohesion between-25 kN/m2 with intervals 5 kN/m2, and internal friction
angle between 20o-45o intervals 5o. Maximum terrace width count conducted for
each combination of these variables. Formulation of the maximum terrace width
is done by multiple linear regression methods, linear nin and a combination of
both. Determining the best formula is based on the value of the correlation
koofisien. Results formulations have two formulasis the formula for the maximum
slope of the natural slope and a maximum width of the terrace on a slope.
