摘　　要：变形监测不仅对监测工程建筑物的安全、防止事故发生等意义重大,而且对积累监测资料、检验工程设计是否合理等也具有重要作用。为了发挥常规测量仪器的作用,并根据实体工程对变形监测的要求,采用测量过程简单、计算原理通俗易懂、精度满足要求的前方交会三角测高法进行变形监测。结果表明:在不同阶段,监测体的最大水平位移、垂直位移与工程设计的理论预应力计算值基本吻合,达到了监测要求。Deformation is not only of great significance in monitoring the safety of buildings,preventing the accidents,etc.,but also in accumulating data of monitoring,testing rationality of the design of engineering,etc.In order to make full use of conventional measuring instruments,deformation monitoring through the front intersection triangle altimetry is simple in measurement,intelligible in calculation principle,and can meet the requirements of the accuracy of measurement.The results show that the maximum horizontal and vertical displacement of monitoring body are consistent with the calculated prestress in different stages,which meet monitoring requirements.
