【摘要】：沉降监测在工程施工和运营管理中起到重要的安全保障作用,基准网点的稳定与否直接关系着监测成果是否真实可靠,因此,基准网点的稳定性检验是对监测成果科学分析与准确预报的关键环节。本文讨论了两期观测精度同一性检验方法,分析了平均间隙法和t检验法进行基准点稳定性检验的原理,并且给出了检验流程。最后,通过工程实例验证了两种方法的可行性和一致性,为沉降监测基准点稳定性检验提供了一种切实可行的解决方案。
[Abstract]:Settlement monitoring plays an important role in the engineering construction and operation management. The stability of the benchmark network is directly related to whether the monitoring results are true and reliable. The stability test of reference points is the key to scientific analysis and accurate prediction of monitoring results. In this paper, the method of checking the accuracy of two periods of observation is discussed, and the principle of the mean gap method and t test method for checking the stability of datum point is analyzed, and the flow chart is given. Finally, the feasibility and consistency of the two methods are verified by an engineering example, which provides a feasible solution for the stability test of the settlement monitoring datum.
