Karakteristik Sifat Mekanis Dan Fisik Tanah Lunak Di Kabupaten Rokan Hilir Berdasarkan Pengujian Dokenbo Dan Vane Shear
ABSTRACT
Along with the times and the rapid growth of technology created by humans,
many ideas and ideas from building experts have emerged to research further
about the nature and characteristics of the soil according to their respective types.
In accordance with the topic of this research, the type of soil that will be studied
further is soft soil. This study aims to determine the statistical relationship
between physical characteristics and mechanical characteristics based on the
parameter values obtained from these two tools. In this study, an experiment was
conducted to find the characteristics of soft soil in Rokan Hilir Regency using
dokenbo and vane shear tools directly in the field, it is hoped that these two tools
have a relationship that can be compared later. Furthermore, the physical
properties of the soft soil will be tested in the laboratory in order to determine the
property value of the soft soil itself. The test was carried out at 30 points spread
over several locations in Rokan Hilir Regency. From this research, the shear
strength (Su) of the dominant vane shear is 16-20 kPa, with an overall value range
of 4-34 kPa. The dominant dokenbo penetration value range is 301-400 kN/m2,
with an overall value range of 158-1430 kN/m2. The dominant dokenbo shear
angle value range is 21 -25 o, with an overall value range of 9-41o. Based on the
correlation results, the penetration value is directly proportional to the Su value,
the correlation between penetration and shear angle has a very low relationship,
the correlation between penetration and physical properties has a low relationship.
