| Abstract: | According to the idiographic complexion of box-beam construction, find out the main reason causing the blocked corrugate pipes and the idiographic position. Pass the theoretical calculation, adopt subsection tensioning, by way of check and accept after completing the load meet the designed requirement after treatment, it points out protection of waving tube should be emphazed in construction of back-force method, which has a certain refering value. |
