Material calculation

(1)桥架：别离计算出各种类型标准桥架的全长，除一该桥架的标准长度，得出桥架的数量外，再添加1%－2%的余量。

(1) Bridge: The total length of each type of standard bridge is calculated separately. In addition to the standard length of the bridge and the number of the bridge, 1% - 2% of the allowance is added.

(2)立柱：如选用一致标准的立柱，可用桥架全长除以均匀立柱距离，得出立柱数，再添加2%～4%余量。如立柱标准纷歧，则需别离计算。

(2) Pillars: If a uniform standard column is selected, the total length of the bridge can be divided by the uniform distance between the columns, and the number of columns can be obtained, and then 2%-4% surplus can be added. If the standard of column is different, it is necessary to leave calculation.

(3)托臂：桥架全长除以托臂均匀距离，再添加1%～2%余量，极为总需量。

(3) bracket: the length of the bridge is divided by the uniform distance between the brackets and the additional 1% ~ 2% allowance.

(4)其它部件：按其主体数乘以必定份额(视总厂而定)求得其总数。

(4) other components: the total number is multiplied by the number of its principal parts (depending on the total plant).
