摘 要: 应用三角高程测量原理研究出一种虚拟观测墩技术,用来代替在实际固定观测墩上对变形体进行的周期性沉降监测,以解决由于工程环境条件所限无法在基准点上建立固定观测墩,或者不希望建立固定观测墩而又希望达到具有高精度仪器水平的高精密沉降监测的目的。在正式监测开始之前,先取得虚拟观测墩后视点的初始观测值。开始正式监测时,在基准点上架设全站仪,对后视点进行观测,然后根据后视观测值用数学的方法精确求得全站仪的架设高度,即仪器高。研究结果显示:该方法得到的沉降监测效果与实际固定观测墩相当。
关 键 词: 工程测量技术;虚拟观测墩;观测墩;全站仪;仪器高;三角高程测量

Abstract: Trigonometric leveling principle was applied to develop a virtual observation pier technology, which was used to replace periodic subsidence monitoring for the deformation body on the actual fixed observation pier. The purpose was to achieve precise subsidence monitoring with high accurate instrument high when a fixed observation pier can’t be set up on the reference point due to the engineering environmental conditions, or a fixed observation pier is not required. The initial observation value of virtual observation pier backsight point was firstly obtained before the formal monitoring beginning. When formal monitoring was carried out, the total station was set up on the reference point then the backsight point was observed. The height of total station was obtained accurately using the mathematic method, on the basis of the observed value. The results showed that the effectiveness of subsidence monitoring was equal to that of actual fixed observation pier.
Key words: engineering survey technology; virtual observation pier; observation pier; total station; equipment height; trigonometric leveling
