摘　　要：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,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。Subsidence monitoring in construction and operation management plays an important role in securityand the stability of the benchmark network is directly related to the authenticity and reliability of the monitoring results,therefore,the stability of the benchmark network test is a key to analyze monitoring results of scientific and forecastaccurately.This paper discusses the two precision consistency check methods,analyzesprincipleof the average interval method and t-test datum stability inspection,and gives the inspection process.Finally,the paper verifies the feasibility and consistency of two methods through an engineering example,and provides a feasible solutionfor subsidence monitoring datum stability test.
