摘要
对矿井井架基础沉降量进行观测,其监测基准网的重要性和特殊性使其对基础网的选取及稳定性都有较高要求。本文从对近代平差基础理论和测量平差中的统计假设检验原理入手,讨论监测基准网的选取及稳定性。结合某矿井井架基础沉降监测网实例,采用秩亏自由网平差和统计假设检验的F检验法,由实测数据解算可得点A1,A2和A3相对稳定,可组建为井架基础沉降监测基准网。
To observations of Mine derrick foundation settlement observations, he the select and stability of basis net have higher requirements on because of its importance and the particularity, start from the principle of statistical hypothesis tes- ting modern adjustment of the basic theory and measurement adiustment in this paper,In addition discuss benchmarks for monitoring network selection and stability. Combine with a mine derrick foundation subsidence network instance, using the F test of rank defect free network adjustment and statistical hypothesis testing,According to Solver the measured data , points A1, A2 and A3 can be set up benchmarks for monitoring network .
