論文概要本論文では、3回連続して発生した地震を受けたシルト質地盤上の実際のTNF(Tender Net Foundation)の動的解析を行いました。2回目の地震後にTNFの沈下量が測定されました。シルト質地盤はUBC3D-PLMモデルでモデル化され、現場から約10km離れた地点で記録された地震加速度が、動的解析における入力加速度として使用されました。地震中および地震後のTNFと地盤の応答を解析し、数値解析は測定された沈下量を良好に再現しました。In this paper, the dynamic analysis of an actual TNF on the silty ground subjected to three consecutive earthquakes is conducted. Measurements of the settlements of the TNF were made after the second earthquake. The silty ground is modeled by the UBC3D-PLM model. Ground accelerations recorded about 10 km away from the site area are used as the input accelerations in dynamic analyses. The responses of the TNF as well as the ground during and after the earthquakes are analyzed. The numerical analyses simulated well the measured settlements.
