ANALISIS STABILITAS LERENG PADA RUAS JALAN BLANGKEJEREN - AWEAUNAN KABUPATEN GAYO LUES PROVINSI NANGGROE ACEH DARUSSALAM
Abstract: Roads Blangkejeren -
Laweaunan is a one-lane road transport in the Province ofNanggroe Aceh
Darussalam, which has an altitude slopes varying between 3.5 to 4.3 m.
Earthquakes, rainfall and altitude slopes greatly affect the stability of the
slopes on these roads. The stability analysis aims to obtain a slope stability
conditions that meet safety requirements at Jalan Blangkejeren - Laweaunan Gayo
Lues District of Nanggroe Aceh Darussalam. Slope stability design using the
simplified Bishop method and Plaxissoftware. The use of these methods has given
the ease and accuracy in solving the problem of stability of the slope to meet
the security requirements of slope stability. Based on the analysis of the
simplified Bishop method and Plaxis at Jalan Blangkejeren - Laweaunan STA. 03 +
650, STA. 03 + 700, and STA. 03 + 750 which has a slope of each 63,4°(1H: 2V)
concluded that the slope is not safe, so it needs a change of slope. After the
change of slope on the slopes of the results showed that the slope of 30°-24°,
the slope of qualified safety with a safety factor (STA. 03 + 650), from 1.299
to 1.468 (STA. 03 + 700) from 1.346 to 1.515 (STA. 03 + 750). Based on the
results of the slope stability analysis obtained slope collapse semicircular
arc (rotational sliding). The slope stability are qualified security that
permitted > 1 as recommended by Abramson (1996)
