摘要
根据CSAMT资料的电阻率值、电阻率梯度及异常相态,把异常分为Ⅴ类、Ⅳ类和Ⅲ类,它们分别对应极破碎岩体(Ⅴ级围岩)、破碎岩体(Ⅳ级围岩)和较破碎岩体(Ⅲ级围岩),最后,依据CSAMT资料所解译的异常段落和硬质岩段落分布长度,对所作隧道的4个主要线路方案进行比选,认为C12K线路方案为最佳工程方案。
Anomaly about CSAMT data are divided into three gradations （gradation Ⅴ , gradation Ⅳ and gradation Ⅲ, respectively） corresponding to different level of crushed rock mass according to the resistivity value, resistivity variance and shape of anomaly. Finally, four tunnels （route）in the lines is compared and one of them is recommended in the light of engineering geological condition based extent of anomaly and hard rock about CSAMT data.
