PERENCANAAN ALTERNATIF DESAIN JEMBATAN JURANG GEMPAL KABUPATEN WONOGIRI
ABSTRACT: Pokoh and Jurang
Gempal bridge are the bridges that are located on Wonogiri – Ngadirojo roads
crossing over Bengawan Solo river connecting Wonogiri Regency and Ponorogo
Regency/Pacitan Regency. But in the past 10 years, only one bridge operates and
that is Pokoh Bridge. This is caused by the condition of Jurang Gempal Bridge
that is no longer adequate since it was built in the colonial era, some parts
of the construction aren’t function properly. With only one bridge that is
operating, it oftenly lead to a high traffic density on traffic hours. Thus,
the re-operating of Jurang Gempal Bridge can be the solution of this traffic
density problem that occurred. However, there is a need to do a total change on
the bridge construction by seeing the existing condition and the age of the
bridge that is already too old. Jurang Gempal Bridge was planned to be located
in the existing location that is 2x60 meter in bridge length. The upper
structure of this bridge is using steel frame that is 9.0 meter in width (2x3.5
meter vehicle floor and 2x1.0 meter sidewalk) and 6.0 meter in height.
Meanwhile, the sub-structure of this bridge is using an abutment that the
height is 7.0 meter and a pier that is 9.0 meter in height. The hard soil that
is positioned in 10 meter depth is the kind of a sand soil so the Bored Pile is
used as the foundation of this Jurang Gempal Bridge.
