    • Abstract
  • The monitoring method for deformation force of continuous concrete wall during the excavation processs of a foundation pit is introduced by using the BOTDA distributed optical fiber sensing technology. Through the distributed optical fiber on the continuous concrete wall of steel and H steel, this technology can automatically acquire the data of strain, bending moment, deflection of piles during the excavation process. The monitoring method adopts double-line measurement and has the capability to self temperature compensation.
