摘要
由于在油罐环墙的沉降监测过程中,采用单一闭合环放射式观测,这种观测网型简单,抗差能力小。在满足闭合差要求的前提下,还会出现观测数据异常的情况。当不能判断这种异常的数据是否可以接受时,用一元线性回归法对可疑数据进行检验,是一种简单有效的方法。
In the course of collecting the data of oil tank foundation settlement,radial observation a single closed loop is employed,which is a kind of simple net with poor error resistance.Although the closure falls into the range of allowable error,some observation data are exceptional.One dimensional regression may be used to test data reliability to make sure whether the odd data can be accepted,which is simple and effective.
