In underground concrete structure engineering,dry shrinkage cracking and plastic shrinkage cracking can be alleviated by in-telligent maintenance.At present,most construction projects use manual maintenance,which has some problems,for example,there are some error in humidity identification.Manual maintenance is often non-standard and costly.Maintenance time and degree cannot be con-trolled.The failure of maintenance to play a full role is caused by these problems.Intelligent maintenance system is through the SCM analy-sis control function so that maintenance can realize automation.It also optimizes the maintenance threshold through image recognition tech-nology.And it can conform to the maintenance system on site according to the test design.Ultimately,the difference in temperature and hu-midity between the inside and outside of the concrete can be reduced,the compressive strength can be improved,concrete cracks can be re-duced,and water resources can be saved.
