The concrete abrasion monitoring of water launch constructions is the key and hard factor in hydraulic engineering. With the development of technology, the present concrete abrasion monitoring techniques have made excellent progress; however, there are still some problems, such as the small monitoring range, and it is hard to totally mirror the diploma of abrasion damage. The smart sensing tools based totally on concrete abrasion is greater and extra used in engineering dimension due to the fact of its excessive precision and robust anti-interference ability. Based on the alive analysis accessory for accurate abrasion, this cardboard establishes the aegis ecology association anatomy of baptize barrage structures, selects the abstinent chafe advice of the project, incorporates out coaching modelling thru the education set, and forecasts the take a look at set. Through theoretical evaluation and accuracy verification test, it can be concluded that the smart sensing tools based totally on concrete abrasion can be used to measure the floor modifications of concrete materials, the size accuracy can attain 0.1 mm level, and the monitoring accuracy price can attain 95%, which can meet the necessities of concrete abrasion depth monitoring in hydraulic engineering.
