利用弹性波法对南沙群岛永暑礁南永一井的珊瑚礁灰岩岩芯和其它礁砂土样品进行了弹性波测量,根据测量结果,绘出了礁灰岩弹性波波速随深度变化的关系曲线,并结合永暑礁的发育演化历史、岩石学、地层学、沉积旋回以及古地磁测年,深入研究了弹性波纵波波速的变化规律,以及它与礁灰岩年龄、结构、岩石类型、孔隙度、沉积环境、地质事件的关系。研究结果表明,看似“异常”的弹性波纵波波速值恰是以上诸因素综合作用的结果。弹性波特性的研究在珊瑚礁地质研究中具有重要的意义,并可应用于珊瑚礁结构及稳定性研究之中

从岩体弹性波的传递速度入手,分析岩体中影响弹性波速度的因素有岩体弹性波频率、视速度(除了射线方向以外的任意方向观测到的波速)、岩体中的含水量差异、岩体的结构构造等。用岩体中测得的弹性波速值对岩体的质量进行评价时必然会出现什么是岩体弹性波的真波速及如阿评价和处理测得的弹性波波速值?采用什么方法评价岩体质量?等问题。在明确视速度概念的扩展、岩体弹性波速、岩石弹性波速、岩体的完整性系数几个名词的含义基础上,建议进行岩体质量评价中,采用岩体的完整性对岩体进行结构分类,列出了岩体的完整系数与岩体结构类型、工程地质特征的对应关系。根据岩体波速与岩体力学参数的关系,给出了计算岩体的静弹模和岩体抗压强度的经验公式。
