A kind of real-time simulation and inverse analysis system for temperature and stress of concrete dam is proposed. Firstly,the database,high-performance computing and webpage programming technologies is used to collect various data in real time and form calculation data files. Secondly,the SapTis programs is called to calculate the temperature and stress in real time,and then the intelligent inverse analysis module is used for temperature feedback analysis until the calculation error meets requirement,thus the real temperature and stress can be obtained. Finally,the calculation results are visualized through post-processing module,and the security warning will be triggered according to designed safety factors. The system has real-time,automatic,intelligent and intuitive features,which can realize the real-time,intelligent and rapid analysis and the inverse analysis of concrete on-site pouring quality,and can visually display analysis results and safety warning.
