| 中文摘要: |
| 浅层地下空洞作为地下地质隐患之一,直接影响到人类工程活动。文章通过高精度磁法、大功率激电、高密度电法、地质雷达等物探手段对太原市东山底工程场地的浅层地下空洞勘查,认为大功率激电及高密度电法选取合理的工作方式、参数,能够较好查明地下空洞的形态、埋深等地质情况,地质雷达对完整地下空洞的位置、规模在波像图上有一个较好的反映,为针对浅层地下空洞探测选取合适的物探技术方法起到一定的参考作用。 |
| 英文摘要: |
| The shallow underground vacancy, as one type of the geological hazards, has direct impact on human engineering activities, caused great inconvenience on the human's construction work. This paper analyzes the effect of the high density magnetic method, high-power induced polarization, high density resistivity method, GPR and other physical prospecting methods for the detection of the shallow underground vacancy located in Dongshan Bottom, Taiyuan City. The result shows high-power induced polarization and high density resistivity method could ascertain the shape of underground vacancy by selecting reasonable working parameters and GPR has a good reflection in the location and scale of the underground vacancy on the wave image, which could guide the selection of suitable geophysical techniques for shallow underground vacancy detection. |
