In this study, a hybrid type of proxy calculation model that combines the DMD algorithm and beam theory on elastic beds is developed to construct a robust design method and a real-time control system for large-scale earth retaining works. The proxy model is a linear differential equation, making it easy to apply to optimization theory. It is considered to be an effective method for constructing robust design methods and real-time control models. Four simple ground heterogeneity scenarios were prepared and the effectiveness of the proxy model was numerically verified.
