Model Investigation Of Settlement Data Analysis Under Multi-stage Preloading

At present,most methods to deal with settlement data are rough.Commonly.no error treatment has been taken on observational data,which causes a low precision on results. In addition,these methods rarely consider the case of multi-stage preloading.Several studies has been made to solve these problems:(1),An error processing is present to manage settlement data.Based on fairing filtration theory,a fairing program is compiled to fair the observed data.(2),According to classical consolidation theories,an analysis model of settlement data has been built under conditions of multi-stage preloading. At the same time,the paper deduces the essential character of the model,gets the solution of model parameters and discusses the problems during engineering application of the analysis model.(3),One dimensional consolidation theory of impeded boundary by linear loading is deduced for layered soil,which expands the consolidation theory of impeded boundary. Afterwards,the paper discusses the application of the model for settlement data of layered soil.(4),Several actual projects has been present to illustrate the application of the analysis model.Compared with on-the-spot observed data,the results of the model are corresponding well and the model is easily employed.lt proved that the built model is able to factually simulate the development process of settlement under multi-stage preloading and has important theoretical and practical significance.
