Abstract: Traditional regression model predicts badly when the independent variable has a complex relation with dependent variable. Intelligent model develops fast due to his visibility, networking and easy availability. Based on the measured data of a concrete dam, extreme learning machine was used in dam safety monitoring and a comparison with the operation process and the prediction results by BP neural network and support vector machine for regression was carried out. Moreover, their actual performances and application occasion were carefully analyzed.

Key words: safety monitoring of dam, intelligent model, extreme learning machine, BP neural network, support vector machine for regression
