Existing calculation theories for soil pressure are all based on the two-dimensioned transverse vertical pressure developed on the culvert of the centerline of the highway, and are not suitable to the actual condition. Three-dimension pressure was discussed in this paper, and according to indoor experiments, the various conditions of the soil pressure around the culvert are found out along the longitudinal...
In view of the specific features of the current harmonic monitoring system, especially the difficulty in realizing complex algorithms, a new method which adopts S3C2410 and embedded Linux platform to construct a new harmonic monitoring system is designed in this paper. It also provides graphic user interface by using QT/Embedded library and harmonic compensation system based on the improved method...
