| Abstract: |
| Urbanization and underground space utilization provide a good opportunity to the development of high-precision gravity detection technology. This paper introduces the application of high precision gravity detection technology in urban underground space detection from the viewpoint of gravity detection equipment, intensive data acquisition, data processing and interpretation. It specifies the accuracy of gravimeter and its reading time in case of interference, the acquisition of 3D coordinates and its correction method for terrain, the calculation of abnormal data, the technique of inversion and result interpretation, etc. It can be used for non-destructive detection of urban underground geological structure and distribution of special geological bodies. As an urban green and environmentally friendly method for exploration, it can be seen as a new method to extract the important geological information of urban space detection. |
| Keywords:urban underground space high precision gravimetry high density terrain correction forward and inversion technique result interpretation |
