Those are useful for analysis to understand how dams moved during earthquake. Those records are valuable as the evidence not only to show the behavior of dams caused by but also to retrieve the index to reflect the dynamic property of dams. In this sense, we have applied the concept of seismic interferometry and its method to seismic records of dams to estimate their property of seismic wave propagation and the dynamic proper ties of those structures.\nThis report show the applicability of seismic interferometry for a series of seismic records obtained by existing seismometer of dams, including small earthquake records. Based on analysis for over 1,000 waveforms of acceleration during about 10years, we can retrieve the waveforms of time domain response and its change. We analyzed the change after huge earthquake and its healing process, considering it as relaxation process.\nFinally we showed the first arrival time estimated by seismic interferometry is considered as the travel time between seismometer based on numerical simulation.\nThough we must verify the applicability of this method to the other many dams, this method might be expected to be more useful to estimate the seismic response and its change in dams.","subitem_description_type":"Abstract"},{"subitem_description":"本報は，近年の地震防災上の必要性により整備されてきた農業用ダム地震計の観測記録を対象として，その整理と解析を行う方法について述べたものである。特に農業用ダム地震計観測記録を逐次自動的に読み取り処理するプログラムと，その読み取り結果に地震波干渉法に基づき繰り返し解析を行うことによって，農業用ダムに地震動が与える影響等に関する情報を提示することができる。近年，大規模地震が頻発し，農業用ダムにおいては余震等も含め多くの    地震計観測記録が蓄積されているが, それに対して逐次自動的な解析を行えることも特徴である。例として，東北地方太平洋沖地震の前後で発生した堤体の地震波伝播速度とその緩和過程を 1000 以上の観測記録の解析を元に定量化し解析を行った。緩和過程については緩和時間帯域制限型の対数関数により近似することができた。最後に，地震波干渉法によって評価された伝播時間が，堤体の地震計間の地震波伝播時間に相当することを，数値解析により確認した。一連の地震計観測記録に関する解析手法はプログラムとしてルーティン化可能であることから，現在蓄積されている農業用ダムの多くの地震計観測記録に適用し，網羅的かつ系統的な研究を行うことができるものと考える。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001161","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人
