Abstract: A new method for predicting the bearing capacity of high-rise building foundation under complex geological conditions is proposed to reduce the prediction error. Support vector machine algorithm was introduced in this prediction method, the relaxation coefficient is incorporated, and genetic algorithm was used to optimize the support vector machine, the foundation bearing capacity prediction model was constructed, and the implementation process of the prediction method was designed to realize the foundation bearing capacity prediction of high-rise buildings. The experimental results show that the settlement prediction error of the proposed bearing capacity prediction method is less than 2%, and the absolute error is less than 0.0005mm. This method effectively reduces the prediction error of the bearing capacity of high-rise building foundations and has certain feasibility.
