Summary: | Different and excessive settlements are the principal problem confronting
engineers working on peat soils. These impose difficult designs and construction
conditions, thus it is necessary to know the geotechnical properties of these soils to
enable more practical designs to be carried out. Peat and organic soil represent the
extreme form of soft soil. They are subject to instability such as sinking and slip failure,
and massive primary and long-term settlement when subjected to even moderate load
increase. Buildings on peat are usually suspended on piles, but the ground around it may
still settle. This study will focus on the properties and consolidation test on peat soils
from two areas. Oedometer consolidation test are conducted for both samples taken
from Kota Samarahan and Kuching. Several laboratory tests were also conducted
for.physical, chemical and engineering properties to determine parameters such as
coefficient of consolidation, Cv,,compression index, Cc and coefficient of volume
compressibility, mv. Prior to the experimental tests conducted, the result showed the
similar deformation for both areas. The coefficient of consolidation, Cv showed
decreasing value when subjected to increment of consolidation pressure with time.
Meanwhile, the compression index, Cc was found to have a strong correlation between
moisture content and void ratio. However, the properties and characteristics of peat
varied with their locations and conditions. |
