本文介绍我所声波测井技术在岩质地基勘测中的应用情况.作者自1973年以来在这方面进行了大量的野外工作,为了进一步阐明单孔测井及孔间透射波测井中所遇到的岩体声学问题,先后进行了两次室内模型模拟试验研究.在此基础上,用声学的原理和方法阐述了折射波测井及采用孔间透射波法测量溶洞大小的方法.并介绍这些方法在工程实践中的应用.
This article describes the application of our sonic logging technology in the investigation of rock foundations. The author has carried out a great deal of field work in this area since 1973 in order to further clarify the situation encountered in single-hole logging and inter-hole transmission wave logging. The acoustics of the rock mass came out with two indoor model simulation experiments. Based on this, the principles and methods of acoustics were used to describe the method of refracted wave logging and the method of measuring the size of the karst caves using the transmitted wave between holes. The application of these methods in engineering practice.
