Title:
PILE PERFORMANCE EVALUATION METHOD
Document Type and Number:
Japanese Patent JP2018024985
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To propose a pile performance evaluation method capable of simply evaluating performance of a pile.SOLUTION: A pile performance evaluation method includes acquisition processing S10, estimation processing S12, and evaluation processing S14. The acquisition processing S10 acquires a real displacement of a real pile head at a predetermined frequency on the basis of measured microtremors of the pile head. The estimation processing S12 estimates an estimation displacement of the pile head at the predetermined frequency on the basis of measured various elements of the ground. The evaluation processing S14 evaluates performance of a pile having the pile head on the basis of the real displacement and the estimation displacement. The estimation processing S12 includes creation processing of creating a pile/ground spring model by inputting temporary pile various elements and ground spring various elements set on the basis of the microtremors to a previously set pile/ground spring model.SELECTED DRAWING: Figure 2
