Abstract

The invention provides a reinforced concrete member service life prediction method based on chloride ion concentration monitoring, and the method comprises the following steps: obtaining chloride ionconcentrations monitored by a chloride ion concentration sensor with a preset burying depth in a measured reinforced concrete member at different monitoring times, and obtaining chloride ion concentration time series data; based on the obtained chloride ion concentration time series data, calculating the critical service life of the measured reinforced concrete member by utilizing a Fick second law; and obtaining the service life of the tested reinforced concrete member, and obtaining the remaining service life of the tested reinforced concrete member based on the obtained critical service life and the obtained service life. The invention aims to overcome the defects of the existing reinforced concrete member service life prediction method based on chloride ion concentration monitoring.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete structure monitoring, and in particular relates to a life prediction method of reinforced concrete components based on chloride ion concentration monitoring. Background technique [0002] Reinforced concrete components in marine engineering are corroded by chloride salts, and the durability problems are prominent. The service life calculation of reinforced concrete members is generally obtained through the chloride ion penetration process. The common practice is to drill core samples in the protective layer of reinforced concrete members, and grind them layer by layer along the depth direction to obtain the spatial distribution of chloride ion concentration. Combined with the analytical solution of Fick's second law under constant initial chloride ion concentration and constant surface chloride ion concentration, through regression analysis, key parameters such as surface chloride ion...
