Title:
液状化判定のための試料採取装置および方法
Document Type and Number:
Japanese Patent JP5526290
Kind Code:
B1
Abstract:
A sample extraction apparatus for extracting samples from a target ground in order to assess whether liquefaction occurs in the target ground, includes: a casing; a holding sleeve, installed inside the casing, for holding the samples; and a vibrator configured to apply vibration accelerations corresponding to different seismic intensities to the samples in the casing, respectively, after the casing is inserted into the target ground to hold the samples of the target ground in the holding sleeve, so that a different liquefaction condition is provided for each sample, whereby said apparatus is configured such that, after having applied different vibration accelerations to the samples in the casing inserted into the target ground, respectively, said apparatus can resultantly extract the samples so that a liquefaction assessment can be made under a plurality of seismic conditions.
