MANUFACTURING METHOD OF FLUIDIZED SOIL
PROBLEM TO BE SOLVED: To provide a manufacturing method of fluidized soil that enables fluidized soil of desired quality to be manufactured readily using blending test data, even when mud density has changed since the blending test due to manufacturing processes, storage conditions, etc.SOLUTION: A manufacturing method of fluidized soil includes: a testing step in which a blending test is performed using a plurality of test soil samples of which mud density and an amount of added solidification material differ; a mud preparation step in which mud is prepared; an added amount setting step in which the mud density of the mud is measured and the amount of added solidification material is set for obtaining desired uniaxial compressive strength; and a fluidized soil preparation step in which the fluidized soil is manufactured by adding the set amount of the solidification material to the mud. In the added amount setting step, the added amount of the solidification material suited to the mud density of the mud is derived, using a relation between the uniaxial compressive strength and the mud density of the plurality of test soil samples obtained in the blending test.SELECTED DRAWING: Figure 2
