Abstract


Rectangular concrete pool as one of the special structure , widely used in water and wastewater engineering . Rectangular pool structure according to its own characteristics in the design process is usually simplified as : floor, wall and roof were calculated backplane calculations usually distributed ground reaction force is reduced to a straight line , in fact, the pool structure significantly the structure of a space pool backplane ground reaction force is not linear , resulting in the difference between the larger pools simplify the calculation results with the actual force . Rectangular concrete pool foundation interaction and rectangular concrete pool design theory and analysis methods . The finite element analysis software SAP2000 model of rectangular concrete water tank foundation interaction and space . Foundation interaction under winkler foundation model assumes that the spring bearing simulation by finite element model , the change in stiffness of the spring bearing reaction different foundation stiffness , different floor thickness change reaction backplane stiffness . Floor, wall and roof of the pool in the use of plate and shell finite element program object . The analysis pools in different foundation stiffness and floor stiffness foundations reaction force distribution curve . Ground reaction force distribution in the form of finite element analysis results winkler foundation model assumes good agreement , indicating the feasibility of modeling . This study for the better after the pool with foundation interaction analysis provides a reference model and theoretical analysis based on performance .
