Title:
ESTIMATION METHOD OF BASE SHAPE
Document Type and Number:
Japanese Patent JP2022187241
Kind Code:
A
Abstract:
To provide a method in which a variety of base shapes can be estimated with high accuracy.SOLUTION: An estimation method of a base shape includes: figuring out, on one hand, an observed natural vibration mode by applying a FDD method to a response waveform obtained in a microtremor observation while the microtremor observation is performed in an object area; figuring out, on the other hand, a calculated natural vibration mode corresponding to each base shape model using FDM and FDD methods while creating multiple base shape models; selecting a calculated natural vibration mode approximate to the observed natural vibration mode from among the multiple calculated natural vibration modes; and estimating a base shape model corresponding to the selected calculated natural vibration mode as the base shape in the object area.SELECTED DRAWING: Figure 11
