It can be noted that the predicted value is larger than back-analyzed one with a relative error permissible in engineering, which can meet the engineering requirement.
Hence, the formula given in the paper can be used in engineering design to predict soil nail axial force.

There is also high uncertainty in climate change modeling and carbon emission scenarios which brings more complexity when applied to the less flexible nature of most engineering models.
Some records of legacy structures are not available due to poor record keeping practices; thereby some assumptions have to be made based on engineering standards at the period of construction.
