高密度电法一直被广泛应用于公路隧道等线型工程的勘察中。该文通过余姚市某隧道的勘察,在测区地质资料、测量装置、资料解释等方面进行分析研究,有效地查明了隧址区断裂等构造破碎带的位置和产状,风化带厚度,为隧址区的工程评价和设计施工提供了科学依据。经钻探验证,表明高密度电法结论准确,效果良好。
High-density electrical method has been widely used in the survey of highway tunnels and other linear projects. Through the investigation of a tunnel in Yuyao City, this paper analyzes and studies the geological data, measuring device and data interpretation of the survey area, effectively identifying the location and the occurrence of the fractured zone in the tunnel area, the thickness of the weathered zone, It provides a scientific basis for engineering evaluation and design and construction of the tunnel area. Proved by drilling, indicating that the conclusions of high-density electric method accurate and effective.
