摘要
Abstract
It is a necessary working means to exploring the broken and hidden faults of underground rock mass in tunnel geological engineering investigation.Maqin area is a typical alpine and high altitude area.Due to the existence of multiple solutions,a single geophysical method can not accurately characterize the development of poor geological bodies in the exploration area.In order to find out the thickness of the strong differentiation layer on the shallow surface of Maqin Tunnel,the location of hidden faults and the distribution of unfavorable geological bodies such as influence zone,broken weak zone and rock mass integrity,integrated geophysical prospecting methods such as audio-frequency magneto-telluric method and high density resistivity method were used to explore the poor geological bodies in Maqin Tunnel.The geological characteristics of the integrated geophysical prospecting area and the research results of integrated geophysical prospecting show that the integrated geophysical prospecting method can effectively identify unfavorable geological bodies such as shallow surface strong differentiation layer and broken weak zone in tunnel exploration in high cold and high altitude areas.And the accuracy of geophysical interpretation is improved.关键词
