Research On Construction Quality Control Of Rock-Fill Embankment To Railway

This paper mainly studies the prestressed anchor cable pile sheet wall structure as the subgrade retaining structure in static and dynamic effect of structures under earthquake loads force calculation problem. The former for the structure of prestressed anchor cable anti slide pile structure and common pile wall structure of the force calculation, a new calculation method of the structure are derived.The first chapter summarizes the background, significance of the research; the research present condition of support at home and abroad of the pre-stressed anchor cable pile sheet wall structure of the model, discusses the uniqueness and necessity of research on engineering application of this new structure; finally introduces the research methods and research contents.The second chapter mainly introduces the existing two similar support form:structure calculation problem of anti slide pile with prestressed anchor cable and pile wall structure under static condition. Study on the anti slide pile are introduced into the free section and the anchoring section structural calculation; calculation for pile wall structure and anti slide pile and plate in the design process. At the same time, introduces the current commonly used for the analysis of retaining structures under dynamic loads.The third chapter studies the prestressed anchor cable pile sheet wall structure under static loading is calculated; considering seismic loads, the potential slip surface of slope position, slope of the landslide thrust under the action of earthquake load calculation method; Study on slope under seismic loads of pile plank structure stress calculation, compared with the static pile the calculation process, gives the calculating methods of structure under dynamic loading action sheet pile bending moment, shear force.The fourth chapter simulated seismic loads by finite element software ABAQUS, known in the role of different slope under seismic load, pile plate bending moment, shear distribution without anchor structure of. Qualitative analysis of the slope static and dynamic loads response.
