Title:
GROUND STRENGTH ESTIMATION METHOD, AND GROUND STRENGTH ESTIMATION PROGRAM
Document Type and Number:
Japanese Patent JP2021085199
Kind Code:
A
Abstract:
To provide a ground strength estimation method capable of estimating reliability in a probability theory even when loading which reaches the ultimate bearing capacity cannot be carried out.SOLUTION: A ground strength estimation method comprises: a step S1 of measuring a load and a displacement in at least one loading step by a flat plate loading test; a step S2 of modeling a load displacement relationship by using a Weibull curve and setting a prior probability distribution to generate a plurality of load displacement curves; steps S3, S4 performing Bayes update by a relationship of the load and the displacement measured by the flat plate loading test to the plurality of load displacement curves to obtain a posterior probability distribution; and a step S5 of obtaining a characteristic value of ground strength from the finally obtained posterior probability distribution.SELECTED DRAWING: Figure 1
