应用超声波法和陆地声纳法测量松弛带厚度

Measuring the Depth of Loose Stratum with Ultrasonic and Land Sonar

介绍了在某工程中将陆地声纳法作为主要方法结合超声波法测量松弛带厚度的一个实例。由于在这项工程中应用超声波法测量松弛带厚度遇到了很大的困难 ,为了能够很好地完成这项工作任务 ,选用了陆地声纳法代替超声波法测量松弛带厚度。在全面应用陆地声纳测量之前先做了几组对比试验 ,确定了它用来测量松弛带厚度的可行性。通过在这项工程中的应用发现 ,两种方法结合使用取得了很好的效果 。

In this paper a project example measuring the depth of loose stratum is introduced. In this project we mainly use land sonar. It is very difficult to measure the depth of loose stratum with ultrasonic. In order to complete the task, ultrasonic is replaced with land sonar to measure the depth of loose stratum. Before application of land sonar to measure the depth of loose stratum, several tests are done to prove that it is feasible.By combining these two methods the good results were obtained. They can make a better effictiveness and raise efficiency.
