Title:
根固め部の強度推定方法
Document Type and Number:
Japanese Patent JP6891062
Kind Code:
B2
Abstract:
To provide a strength prospect method for a foundation part which does not require creation of a concordance table between establishment fields.SOLUTION: The method comprises: a step of obtaining a first correlation between a mass ratio of cement and water in a sample and compression strength after solidification of the sample; a step of obtaining a second correlation between a degree of deviation from the first correlation in a correlation between a mass ratio of the cement and water upon cement milk is mixed with soil material having a previously determined small particle diameter and the compression strength and a mass ratio of the soil material whose particle diameter is a previously determined small particle diameter; a step of injecting the cement milk into a bottom part of a dug pile hole so as to recover it as an unsolidified sample; a step of obtaining a mass ratio of cement and water in the unsolidified sample; a step of obtaining a mass ratio of excavated soil which is included in the unsolidified sample and has a small diameter; a step of obtaining a third correlation between compression strength of the unsolidified sample after its solidification and the mass ratio of cement and water in the unsolidified sample; and a step of prospecting compression strength of a foundation part 32.SELECTED DRAWING: Figure 6
