ANALISIS STABILITAS LERENG DAN ALTERNATIF PENANGANANNYA: STUDI KASUS LONGSORAN PADA RUAS JALAN PRINGSURAT KM. MGL. 22+631 – 22+655 KABUPATEN TEMANGGUNG
ABSTRACT: This thesis
contained about the stability of the soil and it countermeasures on roads
Pringsurat KM. MGL. 22 +631 - 22 +655
District of Temanggung. Pringsurat landscape is hilly mountainous and prone to
landslide. This road section is a class II national road built to connect
cities in Central Java such as Semarang, Temanggung, Magelang with the cities
of Yogyakarta. This road crosses the hills that contain layers of silt soil,
clay, and sandy. Landslide occurred on roads Pringsurat KM. MGL. 22 +631 - 22
+655 District of Temanggung. The data used in this case study is primary data
and secondary data. Data collection was conducted using interviews, direct
observation in the field, and method literature. Method of analysis in this
thesis is to calculate the slope stability and provide solutions to the
problems that occur. Geotechnical analysis done in two ways, with the manual
method and the program. Manual analysis method by Whitlow (1995) for multilayer
soil while the program analyzes using Plaxis software V.8.2. Model of elastic
and plastic collapse of Mohr-Coulomb criterion chosen as a model soil. The
analysis showed that the landslide occurred at KM. MGL. 22 +631 - 22 +655. To
deal with such matters tried with two alternatives, namely the handling of
avalanches with geotextile type BW250 Woven and boored Pile, where the two
alternatives are able to cope with the handling of landslides as evidenced by
the results of the Safety Factor values 1.4114 and 1.4617 for Geotextile for
boored Pile.
