According to the model, the deflection and main pre-brace parameters are illustrated with the Jinsong station of the tenth line in Beijing. It demonstrates that the curve shape of theoretical result, computing result and the on-set measure result are uniform in the main and the change law is similar; that the circumferential space of pipe-roof has a optimum value while satisfying the pre-brace function; that the relation between diameter of steel pipe and flexibility of barrel vault meets negative exponential function. And the diameter of steel pipe has a optimum value.
