The Analysis Of Slope Of Reservoir Bank Stability Based On Heavy Haul Train Dynamic And Seismic Dynamic

Reservoir bank failure as a natural geological disasters has extreme destructive power and great damage scope.After reservoir bank failure triggered by adverse external factors, collapse and other forms of damage always occur, resulting in incalculable loss. Therefore, the research on the slope of reservoir bank stability under the influence of different external factors is necessary, and will show great theoretical value and applicability for disaster prevention and normal operation of construction in the reservoir area.Based on the engineering project of the reservoir bank in the bridge site of Qianyozi Reservoir Bridge, and combines investigation about natural geography, topography, stratigraphic lithology, hydrogeological conditions, geological structure with seismic, summing up the reservoir bank types exist in reservoir area and the external influence factors of the reservoir bank stability.Applying the calculation methods respectively, and analysising the slope of reservoir bank stability under the different external factors for the two type reservoir bank structures.With the different earthquake intensity and the different reservoir water level conditions, the stability of granular mixtures slope of reservoir bank exist in bridge site of Qianyaozi Reservoir Bridge is analyzed. Based on the discrete element theory, the stability discriminant basis is put forward to judge the stability of the granular mixtures slope of reservoir bank. Under the framework of the pseudo-static method principle, analysising the stability difference of the granular mixtures slope of reservoir bank exist in bridge site under the different earthquake intensity and the different reservoir water level conditions using the discrete element software(PFC2D). Then providing technical reference for the stability analysis of the similar granular mixtures slope.Based on the FLAC3D principle, analysising the continuous rock slope of reservoir bank stability under the influence of heavy haul train dynamic load. Gettng the heavy haul train dynamic load at bottom of the track bed by numerical simulation technology of the vehicle-bridge coupling system. Determining the dynamic load acting on the continuous rock slope of reservoir bank according to attenuation rule of dynamic wave in the concrete structure,and analysising stability of the continuous rock slope of reservoir bank.Based on the coupling technology of FLAC and PFC2D provide by Itasca company, by taking the continuous rock slope of reservoir bank and granular mixtures slope of reservoir bank exist in the bridge site of Qianyaozi Reservoir Bridge as athe research object, analysising dynamic effect of the coupling model, then providing technical basis and reference for the certain analysis of the stability of the slope structure.
