地下レーダ探査を用いた人工海浜の空洞化調査: 不陸のメカニズムと探査時期について

摘要

A large field survey to detect underground caves on an artificial sandy beach had been carried out by using a ground penetrating radar (GPR) system. Laboratory investigation had been conducted to understand the mechanism of unevenness on the artificial sandy beach. Then proper time of surveying on the artificial beach has been considered by consistency of the results between the laboratory investigation and the GPR survey.%人工海浜の空洞化調査において地下レーダを用いて広域的な調査を実施した。人工海浜の「砂浜」で発生する不陸のメカニズムを解明するために室内実験を行い、地下レーダ探査の結果と整合させ、現地での探査時期について考察した。
