How is the sideways deformation of the gooseneck tunnel plate measured?

The sideways deformation of the gooseneck tunnel plate is measured from an undamaged area to ensure that the measurement reflects the true deformation without being influenced by any pre-existing damage or distortions. By measuring from a section that has not been affected, it provides a more accurate indication of the structural integrity and performance of the gunnel plate under load conditions. This approach helps assess whether the deformations fall within acceptable limits defined by industry standards and guidelines.

When measurements are taken from undamaged areas, it eliminates confounding factors that may arise from previous wear or physical alterations, thus ensuring that the data collected is relevant and can inform necessary maintenance or repair actions accurately.
