摘要
Abstract
High density resistivity and ground penetrating radar(GPR) method are applied to exploration of horizontal position and depth of a number of underground concrete pile foundations at an electric field in Shanghai, Based on Synthetic modeling the horizontal and vertical resolution of different method is studied when using the model of several underground high-resistivity conductors. Different arrays is also studied in order to choose the best horizontal resolution and dipole array is finally chosen because of its higher resolution. Concerning the low-resolution of high density-resistivity method, GPR method is introduced to position the top of pile foundation. The final result reveals that the horizontal resolution of high density resistivity method may become higher when using effective array, and the higher-vertical resolution with the GPR method may lead to a more precise interpretation result.关键词
