| Abstract: | The article introduces the general condition of gantry crane foundation,and compares bending moment and shearing force of top cover structure at the time of overloading 20 kPa and wheel-pressure passing spread foundation in origin design,in order to prove whether designed gantry crane fit the requirement of structural bearing capacity,and successfully solves the technical difficulty of station structural overloading caused by gantry crane effect. |
