Temperature control and crack prevention monitoring method of concrete dam

The invention discloses a temperature control and crack prevention monitoring method of a concrete dam, and the method has the advantages of accuracy in prediction, wide application scope and real-time early warning. The method comprises the following steps: (1) according to a temperature control factor machine learning theory, establishing a support vector machine model to obtain a temperature field in scheduled future time; (2) determining prediction temperature data and prediction stress data in the scheduled time interval by using a simulation analysis method; (3) determining the control index and curve of the temperature and the control target and curve of the stress according to the simulating operation and a field test; (4) determining a temperature control early-warning curve according to the field temperature control implementation situation and the discreteness of the concreting quality; (5) determining a stress control early-warning curve according to the discreteness of the concreting quality; and
