| 摘 要： | 通过InSAR监测技术与水准测量技术进行对比研究,可以验证InSAR技术在建筑变形监测中的可行性,为建筑变形监测提供新的监测方法,保障施工过程的顺利进行。本文通过两种方法在高层和超高层的工程应用,对两种方法进行分析和比较,得出两种方法测得的沉降趋势基本一致:沉降值最大差值约12 mm,年平均沉降最大差值5.5 mm/年。InSAR监测技术相对于水准测量技术,具有范围广、成本低、监测点密度高等优点,是一种可行的建筑变形监测方法。

| Abstract: | through the comparative study of InSAR monitoring technology and leveling technology,we can verify the feasibility of InSAR Technology in building deformation monitoring,provide a new monitoring method for building deformation monitoring,and ensure the smooth progress of the construction process.Through the application of the two methods in high-rise and super high-rise buildings,this paper analyzes and compares the two methods,and concludes that the settlement trend of the two methods is basically the same,the maximum difference of settlement value is about 12mm,and the maximum difference of annual average settlement is 5.5mm/year.Compared with leveling technology,InSAR monitoring technology has the advantages of wide range,low cost and high density of monitoring points.It is a feasible method for building deformation monitoring. |
