- Ground settlement is a critical issue in underground construction. Ground settlement prediction is important to identify serious damage to adjacent structures caused by settlement exceed the standard. However, conventional methods have some limitations due to nonlinearity and non-stationarity of settlement data. This paper proposes a hybrid model based on empirical model decomposition (EMD) and relevance vector machine(RVM) regression optimized by particle swarm optimization (PSO) designated as EMD-RVM. EMD is used to decompose the ground measured settlement time series into several stationary components called intrinsic mode functions (IMFs). Then, SVR is applied to predict the components independently. At last, the expected prediction values are the sum of all components prediction value at the same time. In order to validate the performance of the proposed method., the signal support vector regression(SVR), signal relevance vector machine(RVM) regression, relevance vector machine based on wavelet transform(WT-RVM) are used to be compared with root mean square error (RMSE) and mean absolute percentage Error(MAPE) are used to evaluate these models. The evaluation results indicate the method proposed is effective and practical.
