摘要
随着高层建筑物越来越多,深基坑高程传递是其沉降观测要解决的重要问题。悬挂钢尺法由于其操作简单、结果精确、可靠性高的特点,在工程中得到广泛应用。本文结合工程实例,对悬挂钢尺法应用于深基坑沉降观测进行深入研究,实践证明悬挂钢尺法能够满足高等级沉降观测高程传递精度要求,对同类项目具有典型示范意义。
With more and more high-rise buildings, the elevation transmission of the deep foundation pit is an important problem to be solved in the settlement observation. Suspended steel tape because of its simple operation, accurate result and high reliability, has been widely used in engineering. Combined with practical engineering, this paper studies deeply on the suspended steel tape used in the settlement observation of deep foundation pit. Practice has proved that the suspended steel tape can meet the elevation transfer accuracy requirements of high level of settlement observation. Finally, it has a typical demonstration of the significance to the similar project.
