可控源音频大地电磁法在工程隧道勘查中的应用

Application of CSAMT in Tunnel Exploration

可控源音频大地电磁测深法(CSAMT)以其探测深度大、分辨率高等特点广泛应用于隧道前期勘查、地下水资源勘查、金属矿产勘查、石油勘查等领域,可取得常规电法和地震法无可比拟的勘查效果,尤其适用于确定地质构造的位置、大小、破碎程度、地质界线等;文中介绍了方法的原理特点,并通过实例证明其方法的有效性。

CSAMT with its characteristics of big exploration depth, hiqh resolution has been widely used in pre -tunnel investigation, groundwater resources investigation, oil survey est. fields, which can make better result than the conventional method and the seismic method,specially used in the position,size,damage and geological boundaries of geological structure. The thesis introduces the characteristics of this method and proved its effectiveness through the practical examples.
