More attentions are paid for the settlement in ground and of buildings caused by subway construction. There are important significant that the extent of the settlement in ground and of buildings around the subway sites monitored and analysed . In order to denoise data based on wavelet, the settlement data are taken as an input signal sequence in which contains Gaussian noises. The A'trous algorithm about wavelet are used in denoising the monitoring data. There are three phases used in the building settlement analysis. The logarithmic function has been used for approximating and predicting the current of building settlement,in phase of rapid subsidence of soil. The results show that the approaches given in our research projects is very perfect.
