摘要
在观测高层建筑物的倾斜变形量时,施工场地往往受限严重,视线受到遮挡,工作人员无法靠近建筑主体结构,这使得传统的经纬仪正交垂直投点标定法很难顺利实施。基于以上问题,本文提出一种测量建筑物倾斜变形量的新方法,详细论述了测量原理,推导出了一种新的建筑物倾斜度计算公式,对其进行了精度分析。通过工程实例验证得出,该方法简单易操作,受场地影响小,具有较高的精度,并在一定程度上提高了工作效率。
When observing the inclination deformation of high-rise buildings,the construction site is often severely restricted,the line of sight for measurement is blocked,so the monitoring points can not be observed by instruments,and sometimes the surveyors can not get close to the main structure of the building,which makes it difficult to implement the traditional theodolite orthogonal vertical projection calibration method smoothly.In view of the above problems,this paper proposes a new method for measuring the inclination deformation of buildings,discusses the measuring principle in detail,derives a new formula for calculating the inclination of buildings,and analyzes its accuracy.Through the verification of engineering examples,it is concluded that this method is simple and easy to operate,less affected by the site,has high accuracy,and improves the work efficiency to a certain extent.
