| 摘 要： | 通常不同岩性的声波速度不同,同一岩性因裂隙发育和风化程度不同,声波速度也不相同。声波测井技术就是依据岩层的这一特性,划分不同岩层及岩层的风化破碎程度。这里对某铁路线的勘测的声波测井结果进行统计分析,给出了测区钻孔揭露的主要岩石较完整状态的声波波速统计值和异常发育概率统计。

| Abstract: | Acoustic velocity is generally different from a type of rocks to the other, even so for the same type of rocks because of different degrees of fracturing or weathering, so forming a basis for velocity logging to delineate geological layers and their weathering and fracturing degrees. A statistic analysis of the results of acoustic logging for a railway bed investigation has been made in the paper, and giving the statistic values of acoustic velocities and development probabilities of anomaly for main types of less fractured rocks intersected by drilling. |
