With the rapid development of economic construction and the western development strategy,more and more hydraulic engineering will be built in the western china.In these high dams and large reservoirs,high earth-dam accounted for a considerable proportion.Owing to the complex geological conditions and frequently intensity earthquakes in the western china, the question whether these buildings can be strong enough to resist the earthquake located in earthquake zones is very much concerned about the major issue.Landslide is a common major natural disaster.Every year a number of incidents of reservoir area and dams which occurred on many occasions caused significant economic losses and casualties.The earthquake is the most common external cause.Therefore,studying on the slope failure mechanism,researching on the main features of the structure and devastating destruction of state has great practical significance.The present research is supported by the National Science Foundation Project-study on Joint Research of Yalong River Hydropower Development(NO:50679093).This paper launched test around different measures by use of the shaking-table of DLUT and the main contents of the current research are as follows:(1) Test the basic parameters of non-saturation sand by use of the commonly direct shear apparatus,also the contact surface parameters of sand - reinforced material.The aim is to offer parameters for numerical calculation.(2) A series of shaking table tests are conducted by analogy method.This paper emphasizes the failure behavior and process of high slope,it also emphasizes the research of the improvement of the slope's validity by appending appropriate reinforcing steel bar in the models and the potential influence of the reinforcement length and density to the slip surface, also discusses the influence to the structures.(3) The acceleration and its response of every case is studied in this paper and compare the acceleration amplification of the slope factor increases with the input seismic loading is also discussed.(4) According to the results of shaking table model test,analys the seismic stability of the reinforcement slope from the destructive state and yielded acceleration. |
