某仓库建筑在24厘米砖墙加37厘米外扶墙的承重砖墙上采用了12米跨双曲抛物面砖拱屋盖。该屋盖是1/2砖砌体按不同的高跨比的两条抛物线:即抛物线z_1=4f_1/b~2(b—y)y,沿另一条抛物线z_2=4f_2/a~2(a—x)x移动所形成的空间曲面体。也即按z=4f_1/b~2 A warehouse building adopts a 12-meter-span hyperbolic parabolic brick arch cover on a load-bearing brick wall with a 24 cm brick wall and a 37 cm outer wall. The roof is two parabolic curves with different height-to-span ratios for 1/2 brickwork: the parabola z_1=4f_1/b~2(b-y)y, along another parabola z_2=4f_2/a~2(a -x) x Moves the resulting spatial surface body. That is, press z=4f_1/b~2
