Structural Health Monitoring and Data Processing of Bracing of Foundation Pit

According to the technical feature of foundation pit structural health monitoring and the situation of the tunnel construction engineering project, a combination monitoring technique equipped by modern GPS technology and traditional survey methods is recommended. The efficient model focuses on the importance of safety monitoring in tunnel constructions. The issues about vertical and horizontal displacements incline deformation monitoring, network setting for foundation pit health monitoring, and processing are discussed in detail. The modern GPS technique is highly efficient for the reference network building while traditional survey method are usually limited by the condition of construction site. With the help of GPS technique, work efficiency and precision can be improved, and project quality will thus be guaranteed. The monitoring data analysis at the end of this paper not only demonstrates the necessity of safety monitoring, but also raise important questions for the structural health monitoring of foundation pit. These are very worthwhile reference for similar cases.
