爆破方法识别滑带试验研究

以往对滑坡体中软弱层与滑带的识别主要依赖于钻孔并辅之以工程师的经验。采用在钻孔中进行爆破的方法，通过对地表接收信号的波形分析即可十分方便地识别出软弱层与滑带。简要阐述了该方法的理论依据，通过对现场爆破实验测量信号的分析可以发现，该方法可以减少钻孔数量以及提高滑带识别的精度与效率。

Study on identification of slip surfaces for landslides by blasting

The identification of slip surface for a landslide is mainly based on drilling holes combining with experience of engineers. A brief method to identify weak layer or slip surface existing in a slope is presented by analyzing vibrating signals induced by blasting. The vibrating signals is collected from earth surface in the vicinity of blasting center. At first, the theoretical base of the method is briefly described. By analyzing the signals from in-situ testings, we conclude that the number of drilling holes can be reduced; and the precision for identification of slip surface of a slope can be improved by using this method.
