Full-Scale Segment Model Test and Stress Analysis of Abnormally Shaped Anchorage Zone of Cable-Stayed Bridge Pylon
The anchorage zone of pylon is the key part of the cable-stayed bridge, and it is also the difficult and important part in designing and construction of cable-stayed bridge. Especially for an abnormally shaped anchorage zone, it is hard to analyze the actual stress distribution on the bridge pylon by a simple mechanical method. The full scale segment model test of the abnormally anchorage zone of Maling River cable-stayed bridge pylon was described. In the test, the cracks, stress and deformation were observed and analyzed. Further more, the finite element analysis for the segment model was carried out. Through the contrast analysis between the model test and the finite element analysis, some important conclusions are drawn such as the model test and the finite element analysis have a good agreement, “the joints outside” and “the polyline inside” are the easy cracking zones, the cracking resistance coefficient of the model is no less than 1.3 and the destroy safety coefficient is no less than 1.6, which can provide important theoretical basis for the design and construction.
