高密度电法在岩溶路基勘察中的应用

高密度电阻率法勘探以其生产成本低,工作效率高等特点,在工程地质勘察中得到了广泛的应用。高密度电法采取较密集的测点以及多种装置的组合同时测量,可提供丰富的地电信息,有利于数据资料的处理与解释。这里在分析高密度电阻率法所基于的静电场理论的基础上,归纳溶洞、滑坡、断裂等地球物理特征,结合某高速公路的高密度电阻率法勘探资料,给出了不同地电模型的异常分布情况,提出了一些提高探测能力和解释精度的数据处理分析方法。通过实例证明,这些方法的正确性以及在实际应用中的良好效果,充分展现出了高密度电阻率法在当今工程地质勘察中所发挥的重要作用和优越性。

Application of high density resistivity method to the exploration of karst cave under roadbed

Due to the features of low cost, high efficiency etc, the high density resistivity method is widely used in engineering geological exploration. By laying dense detectors and measuring with many implements assembled, the method can provide abundant geoelectric information which is used for data processing and interpretation. Based on the analysis of electrostatic field theory, this article concludes the geophysical characteristics of the Karst cave, landslide and fracture from the data of the highway geophysical exploration, and provides some ways to improve exploration ability and interpretation precision. The results well proves efficiency of the method in engineering geological exploration.
