| Abstract: | Dam deformation monitoring is a high precision work. As a very commonly used monitoring method, normal and inverted plumb line plays an important role in dam deformation monitoring. This paper first introduces the principle and method of normal and inverted plumb line. By collecting huge data through normal and inverted plumb at four obser vation stations in Geheyan Dam, it mainly analyses the relationships and changing rules between dam horizontal displace ment and environment variables. According to the experimental results, some important conclusions have been drawn. Last, the paper proposes some improvement measures about normal and inverted plumb line method. |
