Device for measuring displacement and stress of a deep part of pile in the pile loading experiment, and method of measuring displacement and stress of a deep part of pile using the same

摘要

The present invention relates to a device for measuring a displacement and a stress at a specific point in a pile such as a pile tip at the time of carrying out a pile load test, and a method for measuring the displacement and stress of the pile using the device. Since the displacement and stress of the pile are measured by using the apparatus for measuring the displacement and stress of the pile according to the present invention, there is no flow of the measuring rod. Therefore, the displacement and the stress at a specific point in the hollow pile such as a steel pipe pile or a concrete pile It is possible to measure accurately and it is also easy to install and dismantle the apparatus.
