摘　　要：在变形监测过程中,需要建立相应的基准网,基准网可能会因某种因素而发生变形,故也需要对其进行稳定性分析。结合工程实例,通过对某监测基准网的两期监测结果进行平差计算,利用限差法和平均间隙法找出不稳定点,避免使用不稳定基准点给分析计算带来偏差,提高了变形分析的准确性和科学性,证明了限差法和平均间隙法的有效性。In the process of deformation monitoring,it is necessary to establish the corresponding reference network. The reference network may be deformed due to some factors,so it is also necessary to analyze its stability. Combined with an engineering example,through the adjustment calculation of the two-phase monitoring results of a monitoring reference network,the unstable points will be found by using the tolerance method and the average gap method,so as to avoid the deviation caused by the use of unstable reference points to the analysis and calculation,improve the accuracy and scientificity of deformation analysis,and prove the effectiveness of the tolerance method and the average gap method.
