Analytic Method and Application about Chaotic Foundation Pit Deformation Time-series
Jian Chen · Surveying and mapping · 2011
In this paper,chaos theory are used to study the analytic methods of found ation pit deformation.The data series of foundation pit deformation values are reconfigured in phase space respectively and the observed values at the points of certain time delay are handled as new dimensions.Thereby phase points are formed.The dimension amount of the attractor can be calculated according to the correlation dimension method.Thus,the dynamic characteristics of foundation pit are represented.It concludes that chaos theory offer a new way for foundation pit prediction.
