Analysis on Contact Pressure Distribution and Design Model of Foundation Reinforcement
With an independent foundation reinforced applying section-enlarging plan as an example, the contact stress distributions between foundation and groundsill in 6 conditions were analyzed by finite element method and the pattern of stress distributions were discussed. Variable parameters include values of load on foundation and compression modulus ratio K of new and old foundation. The result showed the ratio of old foundation’s contact pressure to that of new foundation was about equal to the K. Based on the analysis results, consider the two times loading effect, the force diagrams of foundation strengthened were presented.
