Abstract

Abstract:

The accuracy, safety and effect of nonruler tunnel deformation measurement technology are analyzed, and nonruler measurement technology is compared with ruler measurement technology, so as to fully recognize the error of nonruler measurement technology used in tunnel construction. The practice shows that nonruler measurement technology is superior to ruler measurement technology. The paper can provide references for similar projects in the future.
