| 摘 要： | 通过对土层深度大于100 m的陕西杨凌试验场地3个不同埋深及形状GNSS观测墩的GPS、电磁波测距及水准观测结果进行比对，定量分析各墩的垂向及墩间距离变化，得出较优的观测墩建设设计方案。结果表明，直接采用土模、埋深8 m的试验墩综合指标最好，带有承重底盘埋深3 m的观测墩次之，埋深5 m的最差。试验结果可为我国西部土层区域同类观测墩建设提供设计依据。

| Abstract: | Based on observations from GPS,EDM and leveling, the deformation of three stations with different depth and shapes is analyzed. The stations are in Yangling, Shaanxi, where the depth of soil is more than 100 m. Comparing the changes of the distance and subsidence between the three stations and GNSS continuous station SNYL, we can choose a better and more reasonable construction design for soil-based stations. The results show that stations with an 8 m depth, which is built directly with soil modulus, has better indicators than others, being more stable and using fewer workers, less material and reduced cost. The station with a 3 m depth is better than that with 5 m depth. The experimental results can provide the design foundation for the same standard of soil-based stations in the western area of China. |
