Study The Temporal And Spatial Laws Of The Deformation And Failure Models To The Landslide With Double Sliding Plane And Reverse Rock-layer

The landslides we study are those with double sliding plane and reverse rock-layer.The interact of the two sliding plane and the antislipping action of the reverse foreside make them have special deformation and failure mechanism,only a few works have been done to study the deformation and failure mechanism of these landslides.The landslide with reverse rock-layer usually belong to creep-sliding landslide,mow most investigations are focus on the high speed landslide but not the creep-sliding landslide.So,it is great important to do some works on studying these landslides.In allusion to a certain landslide in Wuxu segment of Xiangshi Expressway, some works have been done to study the basic characters and formation conditions of the landslide,to find out it's geological genesis,material composition,mechanical properties,structure features and motion characteristics.The law of static and motional landslide are analyzed,the law of temporal and spatial landslide are studied based on these work then are bulit mathematical model. Lastly,do some discussion on forescation of temporal and spatial landslide.Major works are summarized as follows:1.The law of static and motional landslide are systemicaly stduied,form classifion dynamics of landslide,original condition,taking into account double sliding plane analysis stability landsilde,developing sliding zone,coupling rainfall and landslide.2.The character of han jia ya landslide with time are studied by displacement landslide,stability landsilde,and movement mechanics after slided.It is dynamic over time,periodic,progressive character.3.The displacement and the stability of landsilde time series values are divided into a tendency,periodic sequences and random sequences.Respectively,the corresponding mathematical method are used to obtain the model fitting.The model forescation of temporal is gave two useful suggestions,and The use of fitting models to predict landslide displacement.4.The single landslide spatial law is studied and the space forecasting model is improved by useing relative importance.
