The requirements and standards of automation gantry crane running accuracy are very high because the rate of it is much faster than ordinary gantry crane.Researches are requested on how to choose the feasible,reliable and economical form of track foundation and how to choose reasonably the relevant parameters based on the actual situation.By comparison of the current common form of track foundation,with examples and finite element numerical simulation of Yangshan project,a new track foundation type is proposed,dual adjustable track foundation.In the meantime its structure and configuration design is improved.Based on the above researches,the problem of safe and efficient operation of gantry crane without pile foundation on the subsidence prone ground is basically solved.
