Abstract
The rising temperature of the soil by compaction is produced by friction or colhsion between the soil particles.
The relation between the number of compaction and the rising temperature is a continuous curve that has steep gradient at the early stage alld change gradually straight line.The initial part is temperature based on the movement of soil particles by compaction.The other side, straight part of this continuous curve inustrates that the temperature is risen by the crush of soil particles by collision.
And so, we analyzed on the gradient of straight part with minimum square method. In this paper, this gradient are defined as mit rising temperature.
We describe the properties of the unit rising temperature obtained with compaction used 9 species of decomposed granitic soil and 4 comparative experiment soil.
The results of these experimental studies are as follows:
1) the value of the unit rising temperature has relationship with properties of soil particles,
2) unit rising temperature are effectiveness in judgment of weathered degree of the decomposed granitic soil.
