Title:
SUPPORT LAYER REACHING DETERMINATION DEVICE AND SUPPORT LAYER REACHING DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2023175273
Kind Code:
A
Abstract:
To provide a support layer reaching determination device and a support layer reaching determination method capable of highly accurately determining whether a support layer has been reached.SOLUTION: A support layer reaching determination device 30 comprises: a data acquisition unit 32 that acquires drilling recording data composed of a maximum depth of drilling and a value related to drilling resistance of a drilling machine for each preset measurement depth; a memory 31a that stores design soil quality data indicating a relation between the depth and soil quality based on a result of ground survey; an N value estimation unit 35 that calculates an estimated N value by using an N value estimation model including the drilling recording data and the design soil quality data in input elements; and a soil quality estimation unit 36 that estimates the soil quality by using a soil quality estimation model including the drilling recording data and the estimated N value in input elements.SELECTED DRAWING: Figure 3
