提高变形监测初始值精度的定律及相关公式定理

he initial value of deformation monitoring points can be observed by one or more observations are averaged and obtained through the initial value thus obtained may still contain large errors, therefore, be monitored in the monitoring of the early use of the object has not changed Monitoring results to amend its initial value, making it more true value approach to improve settlement and surface displacement monitoring accuracy and reliability. This paper summarizes the initial value for improving the accuracy deformation monitoring the law, so in practical work to master, and in order to avoid the large amount of data transferred from the database call up frequently and to avoid repeating a lot of double-counting process, can accumulate with the cumulative average of two Less correction formula.
