摘要
在西部山区公路的规划设计中,常采用深埋长大隧道贯通隧址区。工程地质勘察中开展地球物理专项作为常用勘察手段之一,音频大地电磁法不受高阻屏蔽影响且对低阻层有较好的分辨率,因此常作为地球物理勘察手段之一。针对西部山区特定的地形、岩性、地质构造及水文地质,建立几类典型音频大地电磁正演模型。通过对西部山区公路深埋隧道音频大地电磁的正演研究,以期野外勘察中采用相适应的合理的野外采集方式,并对数据反演解释提供有力支撑及作为未来提高反演解释水平的研究方向之一。
In the western mountain area highway planning and design,often using grew up in deep buried tunnels are well versed in tunnel site area.Often carry out special geophysical as commonly used in engineering geology exploration survey and one of the means,audio magnetotelluric method is not affected by high resistance shielding and high resolution of the low resistance layer,because this often as one of the geophysical prospecting method.This article in view of the western mountains specific topography,lithology,geological structure and hydrological geology,several kind of typical magnetotelluric forward models are set up.Through the forward modeling research,can guide field acquisition device layout,and provides theoretical basis for the inversion interpretation,which can be used as improve inversion interpretation research direction in the future.
