Improved BSTEM iterative simulation method

The invention provides an improved BSTEM iterative simulation method, and belongs to the technical field of bank slope stability modeling and calculation. The method mainly comprises the steps of inputting parameters; calling a TEM (Transmission Electron Microscope); calling the BSM; whether the BSM is repeatedly called or not is judged through the river bank stability; and outputting a simulation result and entering a next hydrological event. According to the BSTEM iterative simulation process provided by the invention, a modeling tool is provided for bank slope stability simulation under multiple hydrological events, and the application condition of the BSTEM is popularized from an independent single hydrological event to a continuous multiple hydrological event, so that the bank slope contour at the beginning of each hydrological event is in a stable state; according to the method, the influence of the unstable contour on the hydrological event effect is eliminated, the problem of initial contour instabili
