1、地球物理综合测井技术在云桂线富宁隧道勘察中的应用张旭刘伟代伟杨文辉中铁二院昆明勘察设计研究院有限责任公司,云南昆明650200摘要:富宁隧道是云桂线重点复杂隧道之一.勘察采用孔内综合测井技术,对孔中三侧向电阻率、自然伽玛、声波速度、自然电位、井液电阻率、井温、井径等进行了测试,为判定孔内地层岩性、岩体完整程度、围岩级别、异常带、放射性、地温等提供了依据,提高了该隧道勘察精度.关键词:地球物理综合测井;富宁隧道;隧道勘察U452.1A鲁波曲线呈。低,在测爿i合,是指软弱夹有较好的对石灰岩等硬质岩呈低波为划分隧道[围岩以Ⅲ~Applicationofthegeophysicalcomprehe
