摘　　要：本文针对某体育馆屋盖结构沉降监测的任务要求,采用了基于经纬仪或全站仪角度观测的非接触式沉降监测方法;论述了其测量原理及详细的作业过程,在论证测距误差及水平位移对沉降量计算影响可忽略不计的基础上,分析了该方法可达到的精度水平。为满足实时性监测的要求,采用Visual Basic语言编制了联机测量程序,实时记录和存储观测数据及计算成果。工程实践表明,该方法能够在水准测量无法实施的情况下,有效解决不易到达变形体的沉降监测难题。In accordance with subsidence monitoring task requirement of a gymnasium roof structure, a non-contact subsidence monitoring method was raised based on theodolite or total station angle observation in the paper. The measuring principle and detailed assignments process of the method were discussed. On the basis of proofing that influence of distance error and horizontal displacement can be negligible when calculating settlement, the achievable precision level of the method was analyzed. In order to meet the requirements of real-time monitoring, an on-line measurement program was designed using Visual Basic. Observation data and calculated results were recorded and stored on the measurement spot. Engineering practice showed that this method could be capable in effectively solving subsidence monitoring problem of not-readily-accessible deformation objects, in which leveling measurement can＇ t be implemented.
