| 摘 要： | 大跨度钢结构建筑物的建设、改造和结构测试时,因荷载量的不断变化会产生顶棚变形,必须进行变形测量。当变形超限时,会严重影响到建筑物的使用安全,从而要求测量工作提供安全保障。本文探讨了采用单向三角高程测量进行顶棚变形监测的作业方法,并在实际应用中获得了比较满意的测量结果。

| Abstract: | When the large steel span roof is constructed,reformed or tested,the varying load can deform the roof,therefore,deformation observation should be conducted.The overloading deformation will affect the building safety,but deformation observation can provide countermeasure to that.In this dissertation,a method for observing roof deformation by one-way trigonometric leveling is discussed,and the observation result should be satisfied. |
