Beijing Wuzi University,School of Information,Beijing101149,China) Abstract;Physical land settlement caused by foundation excavation construction has different factors, ground settlement data is highly nonlinear,so high precision ground settement prediction has certain difficulty. This paper processes the observed data by using the cubic spline interpolation method. The genetic algorithm (GA) is used to find the optimal parameters of support vector machine (SVM) and GA - SVM time series prediction model is established,and these methods which are put in the foundation model of a subway station foundation excavation engineering in Guangzhou is used to predict the ground settlement data,which is pared with the measured values and other prediction methods,this model has obvious superiority,which has great significance for the improvement of safety construction of foundation excavation.
