Abstract: Appling temporary steel bridge is a method of passing bridge which span is not bigness in heavy-cargo transportation.This paper introduces a method with temporary steel bridge combined with original bridge could solve the original bridge not carrying enough capacity.when 323 ton heavy-cargo pass bridge whose span is 16m in Yanjia chemical plant of ehangshou district is applied.This pass programe save much consolidating cost and gained great benefit.This paper introduces the whole design and calculation of temporary steel bridge.

Key words: heavy-cargo transportation;temporary steel bridge;design, practice
