A Discussion on the Whole-Life Monitoring Mode of Large Bridge from Construction to Operation

Abstract

Considering that the health monitoring system and construction monitoring system are not combined flexibly, the whole life monitoring model is conceived. That method is based on data dependence analysis of pre-buried and table-posted sensor, at the same time, correction of monitoring data is also taken into consideration. All the works focus on the research about collaborative work mode of monitoring data from pre-buried and table-posted sensor. This achievement brings so many benefits, firstly, it makes dead loads and living loads are considered together. Secondly, it brings new ideas to guarantee the safety of large bridges in construction or operation. Thirdly, the research results are embodied fully in the engineering practice of Nujiang Bridge.
