不同深度及形状的土层GNSS观测站建设试验
Test of Soil-Based GNSS Stations with Different Depth and Shapes
摘要
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 stationsand 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.关键词
