从1976年开始,我系海洋地球物理勘探教研室曾多次承担了用地震折射方法勘探海岸港湾海底基岩埋深和构造特征的任务。由于海上条件比较困难复杂,有一些技术要求很难达到陆上工作的水平,例如激发点位置不准确就是我们曾遇到的一个困难问题。为了解决这些问题,除了在作业方法上进行过多次革新外,在解释方法上也摸索了一些经验。这里要介绍的一种解释方法就是通过我们的工作总结出来的。 Since 1976, my Department of Marine Geophysical Exploration has undertaken many tasks of using seismic refraction methods to explore the depth and structural features of the seabed bedrock of the coastal harbor. Due to the difficult and complex sea conditions, there are some technical requirements that make it very difficult to achieve the level of land-based work. For example, inaccurate excitation points are a difficult issue we have encountered. In order to solve these problems, in addition to carrying out many innovations in the methods of operation, some experimental experience has also been explored. One of the ways to explain here is to conclude from our work.
