试掘确认が困难な深度1~10尘の埋设物は、ボーリング掘削による探针などが行われ、调査に多大な労力を要している。そのために、この深度の効率的な探査手法の开発が求められており、探査手法の确立のために、深度2.5尘の矩形函渠を対象に反射法弾性波探査手法を用いた基础的実験と数値シミュレーションを実施した。実験の事前検讨として矩形函渠から反射する波を高密度に受振する测定配置と反射点を抽出するデータ処理方法を数値シミュレーションで検讨し、その测定配置とデータ処理方法を実験で适用した。その结果、比较的に精度よく矩形函渠上面の位置を特定することができた。このことにより、本研究で用いた测定配置及びデータ処理方法は、埋设物の探査手法として适用可能であることを确认した。 キーワード: 地下埋设物、反射法弾性波探査、矩形函渠、数値シミュレーション |

Exploration of buried objects at a depth of 1 to 10 m, which is difficult to confirm by test pitting, takes labor for exploration, such as probe by boring. Therefore, the development of an efficient exploration method for this depth is required. In order to establish the exploration method, fundamental experiments and numerical simulations using the seismic reflection method were carried out for the box culvert at a depth of 2.5 m. As a preliminary study of the experiment, the measurement arrangement for receiving the reflected waves from the box culvert at high density and the data processing method for extracting the reflection points were considered by numerical simulation, and the measurement arrangement and the data processing method were applied in the experiment. As a result of the experiment, it was possible to identify the position of the upper surface of the box culvert with relatively high accuracy. From these it was confirmed that the measurement method and data processing method used in this study can be applied as a method for exploring buried objects.
