Title:
LIQUEFACTION STRENGTH CURVE GENERATION METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2016161463
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a highly accurate liquefaction strength curve without the need of a plurality of specimens having less fluctuation of property.SOLUTION: A liquefaction testing device 12 performs a loading test for performing a loading different in stress ratio Ri one or more times for one piece of a specimen, while detecting a strain of the specimen. An acquisition part 18 acquires a loading test result. A first calculation part 20 calculates the energy consumption Wi of the specimen for each loading from a relationship between the stress and the strain for each time of loading. A second calculation part 22 calculates a total energy consumption Uof the specimen until reaching the liquefaction. A third calculation part 24 calculates the number of times of loading repetition Ni of the specimen until reaching the liquefaction when the loading on which the stress ratio Ri acts is repeated by dividing the total energy consumption Ul by the energy consumption Wi for each loading. An output part 26 generates and outputs a liquefaction strength curve by plotting a set of the stress ratio Ri and the number of times of loading repetition Ni.SELECTED DRAWING: Figure 1
