The Retaining Wall Of Pile Foundation Beams Of Design And Application Research

Landslide (smooth, collapse, flow) volcanic eruptions and earthquakes tied for thethree become geological disasters. Landslide and debris flow, landslides geologicaldisasters have serious influence on the safety of life and property of the people. As thegreat western development of continuous, transportation, railway continually to hillsextensions, form lots of rock mass slope engineering, their safety has caused social theuniversal attention. In order to reduce people’s life and property loss, protectionalready built engineering, and the slope stability and retaining structure of the study isvery necessary. In the new retaining structures, the retaining wall on supported beams ofpile foundation as a kind of engineering of the most commonly used one of the preventionand control measures. the retaining wall on supported beams of pile foundation,a newtype of retaining structure is composed of retaining wall and pile foundation beam,hold concurrently retaining wall and the advantages of the pile foundation. Althoughthis kind of structure used in more projects, but its design theory relatively lags behindin practical engineering application, and lizhing software does not have this kind ofstructure design module, prevented the structure applation of use. This paper thestructure of the design theory and application in the research.In this paper，the main jobs are as follows：①The balance in the heavy retaining wall earth pressure of the commonly usedmethod are summarized.The model of beam classification to calculate internal forcecalculation is classified to determine the internal force calculation method beam.And according to the stress of the pile foundation, pile foundation stress analysis ofthe established model, and then puts forward the pile foundation of the internal forceanalysis method.According to retaining pile foundation beam combination ofcomponents form, the paper analyses retaining structure force of the componentsand power transmission mechanism.②According to the first temple chongqing grace slope engineering, thetransfer coefficient method, get the overlying soil slope bedrock the rest of theforce decline, it is concluded that the stability of the slope coefficient. According tothe slope engineering and pile foundation beam combination, retaining theapplication condition and sure to use pile foundation beam on retaining wall’s support. Use of retaining structure internal force calculation method ofcomponents, and from each component stress, strain and bending momentdistribution laws.③The paper set up the first temple of3d slope grace finite element analysismodel. ANSYS software to the retaining structure of numerical analysis, andconcludes that the pile foundation beam retaining wall’s internal components value,and compared with the foregoing calculation method of analysis, and to verify pilefoundation beam retaining wall’s internal force calculation the feasibility of themethod, on the basis of the design scheme is further optimization of pile foundationbeam "retaining retaining structure reasonable design lay the foundation.
