本文介绍了EH4法的探测原理,利用EH4法探测深度大的特点,将其应用到深厚滑坡堆积体的探测工作中。文章以汶川地区一个深厚滑坡堆积体的勘察工程为成功实例,介绍了EH4法在探测过程中数据处理的技术要点、处理方法及注意事项,展示并分析了EH4法在工程勘察中的探测效果,验证了利用EH4法能够揭示深厚滑坡堆积体的厚度和形态,探测场地下的隐伏断层,说明利用EH4法探测深厚滑坡堆积体的厚度和形态是可行的,为今后深厚滑坡堆积体的勘察提供一些经验和帮助。
In this paper, the principle of EH4 method is introduced, and the method of EH4 is used to detect the large depth. The method is applied to the exploration of deep landslide deposit. This paper takes a survey of a deep landslide accumulation in Wenchuan area as a successful example, introduces the technical points, treatment methods and precautions of data processing in EH4 method, presents and analyzes the detection effect of EH4 method in engineering investigation, It is verified that using EH4 method to reveal the thickness and shape of the deep landslide deposit and detecting the concealed faults in the field shows that it is feasible to detect the thickness and shape of the deep landslide deposit by EH4 method, Experience and help.
