The Application of GPS in Dam Deformation Observation

In order to ensure the safe operation of the dam,the stability monitoring is needed. This paper introduces the measurement and monitoring of the reference network by using GPS measurement technique,and analyzes the results of the first or second phase. The monitoring results show that the dam is not fully entered into the period of stability,and the deformation monitoring is also needed. The dam deformation monitoring by using GPS technique can reduce labor intensity and improve working efficiency,which can provide reference for dam deformation monitoring.
