Abstract:

The autogenous volume deformation of concrete is an essential parameter in sorting and analyzing the monitoring data of strain meter, and also is the crucial referencing parameter in the analysis of the deformation and loading situation of concrete components. However, there is no exact conclusion for the generation mechanism of autogenous volume deformation of concrete up to now. So, it is necessary to measure the autogenous volume deformation of concrete, to which, the non-stressmeters are applied generally. Through the case of Jinping Hydropower Station I, the problems in the monitoring of autogenous volume deformation of concrete are demonstrated according to the analysis of the monitoring data by non-stressmeters.
