ANSYS program was adopted on the theoretical analysis. Some val able feat res abo t the long span TSS design were gotten thro gh comparison analyses. Some propositional n merical val e of the parameters mentioned above is provided, and which additional provides some sef l reference for the initial design of Yellow River model testing center b ilding.
