Abstract: The settlement of the pedestal and the differential settlement between pedestals of a precast beam fabrication site on soft soils were analyzed by the commercial finite element software MIDAS GTS.  A total of three different site subsurface conditions were compared. Combining with engineering experience, the analysis results show that the system of beam base (pedestal) on both ends with “quasi” pile foundation, beam middle beam (at the bottom of the pedestal) with expand the foundation of “rigid + soft” design on the base of settlement control and ensure the quality of precast beam effect is better.
