Document Type and Number:
Japanese Patent JP6921701
Kind Code:
B2
Abstract:
To provide a ground investigation method capable of determining the necessity of vibration reduction measures of an earthquake by the minimum required ground investigation.SOLUTION: A ground investigation method of investigating the state of a ground includes: a process (step S1) of preparing a determination database in which a surface-layer ground amplification factor is calculated on the basis of the relationship between the depth to an engineering ground and an average S wave speed of a surface-layer ground; a process (step S2) of obtaining the depth to the engineering ground and the average S wave speed in the ground to be investigated by ground investigation; and a process (step S6) of determining the necessity of vibration reduction measures of the ground to be investigated on the basis of the result obtained by the ground investigation and the determination database.SELECTED DRAWING: Figure 1
