天津港埠三公司7、8泊位卸驳码头于1987年竣工后,因码头前沿线平均向河位移50～60mm,一直不能验收及交付使用。1992年天津港建设公司委托天津港研所,在不损坏码头构件的情况下,做现场整体载荷试验。寻求、探讨和验证已发生较大位移的7、8泊位运行两台M_(10-25)型门机的可能性。通过对码头构件的现状检测、轮压测定沉降位移的观测,及横梁应力和应变测定分析认为:7、8泊位卸驳码头上两台M_(10-25)型门机正常作业,q<10kN/m~2,对修复后的码头构件均无异常变化,属正常运转状态。
After completion of the No.7 and 8-berth jetty terminals in Tianjin Port 3 Company, they were not accepted and delivered for use due to the average river displacement of 50-60 mm to the front of the wharf. In 1992, Tianjin Port Construction Company commissioned the Tianjin Port Research Institute to carry out the overall on-site load test without damaging the wharf components. Seek, explore and verify the possibility of running two M_ (10-25) type door machines with a large displacement of 7,8 berths. Based on the analysis of the status quo of wharf components, the observation of settlement by wheel pressure measurement and the analysis of stress and strain of beams, it is concluded that the two M_ (10-25) type door operators on the 7,8 berth terminals are in normal operation and q <10kN / m ~ 2, no abnormal changes to the dock after repair, is a normal operation.
