综合物探方法在河床深厚覆盖层勘探中的应用

Application of Comprehensive Geophysical Method to Deep Overburden Layer Exploration in River Bed

在深厚覆盖层勘探中,单一物探方法的结果通常可靠性较低。本文介绍了在某水电工程坝址区勘探工作中,采用了地面电测深法、浅层反射法、水上电测深法,在河床深厚覆盖层勘探中取得了较好的效果。实践证明,采用综合物探方法资料相互验证,能提高资料解释成果的可靠性和准确性。

In deep overburden layer exploration, the result of a sole geophysical method is usually lower reliability. This paper introduces the exploration work at the dam site area of a hydropower project, we used ground-based electrical sounding method, shallow seismic reflection method and water electrical sounding method to investigate deep overburden layer in river bed, and we have made the better result. The examples have proved that using comprehensive geophysical methods, using different geophysical results to confirm each other can increase the accuracy and reliability of inference and interpretation of data.
