DAMAGE RATE ESTIMATING METHOD OF PILE FOUNDATION AND DAMAGE RATE ESTIMATING SYSTEM OF PILE FOUNDATION

摘要

PROBLEM TO BE SOLVED: To quickly and inexpensively acquire a damage state of a pile after suffering from a disaster by an earthquake.;SOLUTION: This damage rate estimating system has a step of forming damage corresponding information of associating an inclination with a damage rate by calculating an inclination capable of inclining a pile foundation by vibration on the basis of a pile foundation model of modeling the pile foundation being an estimation object of the damage rate and the damage rate indicating a damage state likely to be generated in the pile foundation by the vibration by a computer with every size of the respective vibrations on the basis of pile damage information set so that damage of respective piles caused by the vibration changes stepwise in response to the size of the vibration when imparting a plurality of kinds of vibrations to the pile foundation, and a step of estimating the damage rate of the disaster-stricken pile foundation on the basis of a measured inclination based on a value of measuring the disaster-stricken pile foundation and the formed damage corresponding information.;COPYRIGHT: (C)2007,JPO&INPIT
