【摘要】 高密度电法在陆地上的应用已经相当成熟,在水域包括淡水水域和浅海水域中的应用相对较少。水域工程相对于陆域工程,勘察技术难度显而易见,作为一种成熟高效的物探方法,高密度电法在水域工程勘察中的应用值得研究。本文通过建立淡水水域和浅海水域地质模型,进行正反演计算分析,应用两个实例证实高密度电法在水底隧道勘察中的应用效果显著,特别是在水底地下低阻构造带、地层界线的划分、基岩面起伏情况勘察方面效果尤为突出,这对水底地下隧道施工提供了很好的支持。更多还原

【Abstract】 High density resistivity method is used much fewer in water area comparing with the popularity in land.The engineering investigation is much difficult in water area than in land.As an effective and ripe geophysical exploration method,high density resistivity is worth studying in water engineering investigation.The geological models are established,including fresh water area and shallow sea area.Forward and inverse calculations are carried on.The calculation results and two cases show that high density resistivity method is outstanding in underwater tunnel investigation,especially in low resistance structure belt,formation boundary division and bedrock surface fluctuation and which will provide a good support to the tunnel construction in water area.更多还原
