摘要
不同的物探方法对不同地质异常的灵敏度不同,电磁法对地质体的导电性反应灵敏,如含水性;地震勘探对断层及破碎带具有很高的分辨率。本文提出了采用浅层地震层析成像法和高密度电法进行隧道工程地质勘察的综合物探技术。从基本原理出发,通过野外数据采集、室内数据处理及成果资料解释等方面详细介绍了综合物探技术的使用方法。应用实例表明,综合物探测试结果能够满足隧道勘察的工程地质要求,在隧道的工程勘察中是一种快速经济并且有效的方法。
Different geophysical exploration methods have different sensitivity of the different geological anomaly. For example, electromagnetic method is more sensitive with the conductivity of the lithological composition, such as water content; the seismic exploration has high resolution with the fault and fracture zones. In this paper, it will carry out integrated geophysical prospecting which are a combination of High density resistivity method and shallow seismic CT exploration. Based on basic principle, the paper described the use of integrated geophysical methods through field data collection, data processing and results of indoor data interpretation, etc. The examples show that the result of the integrated geophysical exploration test can meet the requirements of engineering geology in the tunnel engineering investigation; it is a kind of rapid economic and effective method.
