A practical data recovery method is proposed for the strain data lost during the safety monitoring of mega columns. The analytical relations among the measured strains are derived to recover the data lost due to unexpected errors in long-term measurement during construction. The proposed technique is applied to recovery of axial strain data of a mega column in an irregular building structure during construction. The axial strain monitoring using the wireless strain sensing system was carried out for one year and five months between 23 July 2010 and 22 February 2012. During the long-term strain sensing, three different types of measurement errors occurred. Using the recovery technique, the strain data that could not be measured at different intervals in the measurement were successfully recovered. It is confirmed that the problems that may occur during long-term wireless strain sensing of mega columns during construction could be resolved through the proposed recovery method.
提出了一种实用的数据恢复方法，用于恢复 mega 柱安全监测中丢失的应变数据。推导了测量应变之间的解析关系，以恢复由于施工过程中长期测量中出现意外误差而丢失的数据。将提出的技术应用于恢复不规则建筑结构中 mega 柱在施工过程中的轴向应变数据。使用无线应变传感系统进行了为期一年零五个月的轴向应变监测，时间为 2010 年 7 月 23 日至 2012 年 2 月 22 日。在长期应变传感过程中，发生了三种不同类型的测量误差。使用恢复技术，成功地恢复了在不同测量间隔无法测量的应变数据。通过提出的恢复方法，可以解决 mega 柱在施工过程中的长期无线应变传感中可能出现的问题。
