Study On Cutting Slope Stability Of Motorway

The design standard of motorway is very high,especially in plane, vertical and transect face. Cutting slopes are its most visible view. The stability of slope directly concerns the construction plan and normally management after the completion of projects, sometimes even give great hazard to men's lives and economy. So recent years, it has being looked on as a new important research by more and more people. While to engineering in mineral,irrigation works and railway,Research on slope stability has accumulated quite a lot of practices and experiences, valuablely to cite and consult.By tens of years development,the study on Cutting Slope Stability of Motorway has experienced such a progression: From statistic to dynamic, confirming to unconfirming,double dimensions to three-dimension and from isotropy to anisotropy. Stability analysis methods are very abundant. Based on current research fruits, this context has made a deep study on Hang-Jin-Qv Motorway cutting slope stability,basical work as follows:1) Faced to all sorts of stability analysis methods,this context has generalized the status in quo and its development,and has made a classification systematically.2)Study on motorway cutting slope stability should base reasonablegeological models. To differentiate the slope failure from its deformation,we consider side displacement,squirming and toppling are just forms of deformation,and the slope last failures are just sliding, collapse and flowing. Based on this, this text made a study on influence factors of slope stability,and gave a systematically classification on slope failure models.3)By building geological models and mathe-mechanical models,this context has created a clear valuation approach in research,it concluded geometrical and mechnical integration. Of course,this method showed great significence on Hang-Jin-Qv Motorway cutting slope stability estimation.
