建筑物变形观测方法及实施

Deformation Monitoring and Practice in Construction

传统的变形观测是针对不同性质的变形量分别量测,如沉降变形,倾斜变形,裂缝变形等等。事实上,这些变形量相互影响,一起构成一定量度的空间变形,又可分为平面位移和含高程位移。由于空间点位往往可以用平面坐标和高程的三维值来表示,因而在分析建筑物变形状况时,可用点位的空间变形值来反映实际的变形量。这就是三维方向交会法的基本原理。本文分别阐述上述两种方法的实施过程,并说明了后者的优越性。

Settlement, inclination and cracks deformation are the primary observations in traditional deformation monitoring. These deformation variables affect each other, and constitute one measurement in space, which divide into plane and height displacement. For the point position can be represented by horizontal coordinates and height value, we may use variation of space position to monitor deformation in construct. This is the basic principle of 3D-Intersection. The paper introduces the above-mentioned methods and makes it clear that the latter one has great advantage.
