稠密物理探査技術による浅部地盤構造の把握と3次元可視化技術

摘要

We have developed high-resolution geophysical exploration tools which make it possible to delineate the heterogeneous structures of near-surfaces, including earth structures such as embankments and levees. 3D or 4D geophysical property models were successfully reconstructed owing to dense sensor arrays and time-lapse monitoring. Moreover, we have built a Web3D system for rendering 3D models on the Web. The combination of geophysical data acquisition with high-precision VRS-GNSS positioning is the key to make 3D near-surface models.%盛土や堤防など不均質性の度合いが大きい土構造物内部の構造を詳細に把握することが可能な浅部物理探査技術を開発した。稠密な計測を実施し、さらにリアルタイム精密測位情報と組み合わせることによって、土構造物や浅部地盤の物性構造を3次元的にモデル化し、Web上で表示させることを可能にした。
