| 中文摘要: |
| 余庆至遵义高速公路位于贵州省东北部，地形切割大、地质结构复杂，利用常规方法进行定测勘察，费时费力、成本高、工期长、效果一般，后选用音频大地电磁法(AMT)和钻探相结合的方法，物探结果和钻孔岩性相互对比，相互验证，以点带线，提高了工作效率，降低了勘察成本，并且物探成果可以指导钻探施工，为隧道掘进提供超前预报。该方法在该区取得了较好的效果，通过总结方法的优缺点，可以将该方法在相似区域进行推广应用。 |
| 英文摘要: |
| Yuqing to Zunyi expressway is located in the northeast of Guizhou province, the region with large terrain cut and complex geological structure. The use of conventional methods for measuring survey, it’s too time consuming, high cost, long construction period and the effect is general. But combining the audio magnetotelluric method (AMT) and drilling, geophysical prospecting results and drilling lithology contrast each other, mutual verification, in point with line, can improve the work efficiency and reduce the exploration cost. The geophysical exploration results can guide the drilling construction, providing the advanced prediction for tunneling. The method has achieved good effect in the region, through summarizing the advantages and disadvantages of method, this method can be applied in similar area. |
