Abstract: Effective compaction quality control is crucial to safe and stable operation of earth-rock dams. This paper develops a novel intelligent control theory for intelligent decision-making and automatic control of earth-rock dam compaction. This theory adopts the structure of ternary theory. Based on an artificial intelligence algorithm and operation research, it uses an intelligent decision-making unit to formulate an optimal compaction plan from global perspective; and at its bottom level aimed at a problem of how to control the actuator, it achieves an intelligent control of the compaction process by using the automatic control theory and a double closed-loop control mode. Application examples show this new theory can achieve a successful intelligent control of earth-rock dam compaction and significantly improve compaction efficiency while ensuring compaction quality. It would provide key theoretical and technical support not just for intelligent construction of earth-rock dams, but with application prospects in highways, railways and airports.
