| Abstract: |
Yachihe Bridge is a record-breaking cable-stayed bridge with 800m steel truss deck of main span. It is the first time for cable crane used in the deck erection of cable-stayed bridge in the world. Unusually, the cable crane has no temporary towers but uses the bridge pylons directly. Field load tests are carried out before the cable crane putting into services. The cable crane load tests include static load test and dynamic load test, during which main cable forces, deformations of pylon tips, main cables and anchorages, etc. are measured in situ. Wherein, the cable crane is well instrumented with strain gauges at critical locations of the anchorages to record the main cable forces. This paper mainly describes the design, schemes and instrumentations of the cable crane load tests, meanwhile field measurements and numerical results are presented and compared. |
