Abstract: Some analysis methods in common use at present on rock slope displacement monitoring data such as the method of regressive analysis, the method of time series analysis, the method of grey theory analysis, the method of non-linear dynamics analysis and the method of displacement space-time synthetics analysis, are briefly discussed in this paper. The paper not only studies these methods from several parts such as the keystone, applicable conditions, virtues and shortcomings and so on, but indicates the developing trend of the rock slope displacement monitoring data analysis methods. The paper emphasizes the controlling effects of the rock mass structure to its deformation and failure, and points out that rock slope displacement monitoring data analysis method based on rock mass deformation and failure mechanics is the developing trend.
