    Abstract
  • For the settlement calculation method of the composite foundation based on the assumption of flexible foundation, the calculated value is often larger than the measured value due to the non-uniformity of base reaction distribution under the influence of foundation interaction and the non coincidence between the maximum base reaction and the maximum settlement position. Two composite ground settlement calculation methods considering foundation interaction were studied, including the SFIA method and elastic theory method used in the foundation design module of YJK building software. Foudation settlement calculation was conducted based on the above two methods as well as flexible foudation method. Compared with the flexible foundation method, the calculated values of the maximum settlement and differential settlement of the foundation are smaller and closer to the measured values due to the consideration of the interaction effect of the foundation. The research results can provide reference for the settlement calculation of composite foundation.
