PREDICTED TOPIC OF KEY NOTE: RECENT ACHIEVEMENTS IN THE DESIGN AND CONSTRUCTION OF MULTI-SPAN CABLE SUPPORTED BRIDGES IN CHINA

IN RECENT YEARS, MANY MULTI-SPAN CABLE SUPPORTED BRIDGES HAVE BEEN DESIGNED AND BUILT IN CHINA. AMONG THEM, THERE ARE TAIZHOU BRIDGE, WHICH IS THE LARGEST MULTI-SPAN SUSPENSION BRIDGE, AND JIASHAO BRIDGE, WHICH IS THE LARGEST MULTI-SPAN CABLE-STAYED BRIDGE. TAIZHOU BRIDGE, SPANNING OVER YANGTZE RIVER IN JIANGSU PROVINCE IS A THREE-PYLON TWO-SPAN SUSPENSION BRIDGE WITH THE SPAN ARRANGEMENT OF 390 +1080+1080+390 M. IT HAS A STEEL MIDDLE PYLON AND STEEL BRIDGE DECK. JIASHAO BRIDGE, SPANNING OVER OVER HANGZHOU BAY IN ZHEJIANG PROVINCE, IS A SIX-PYLON CABLE-STAYED BRIDGE WITH THE SPAN ARRANGEMENT OF 70+200+ 5 X 428 +200 +70M. IT HAS THE WIDEST BRIDGE DECK OF 55.6M, AND IS THE LARGEST SCALE MULTI-SPAN CABLE-STAYED BRIDGE IN THE WORLD. IN THIS PAPER, SOME KEY DESIGN AND CONSTRUCTION TECHNOLOGIES OF THE TWO BRIDGES WILL BE PRESENTED. THE FOLLOWING TOPICS INVOLVED IN THE DESIGN AND CONSTRUCTION OF MULTI-SPAN CABLE SUPPORTED BRIDGE WILL BE COVERED: FOR TAIZHOU BRIDGE, (1) VEHICLE LOADING OF MULTI-SPAN SUSPENSION BRIDGES, (2) THE ANTI-SLIDE PROBLEM BETWEEN THE MAIN CABLE AND THE SADDLE AT THE TOP OF THE MIDDLE PYLON, (3) THE CONSTRUCTION OF THE LONGEST MAIN CABLE; FOR JIASHAO BRIDGE, (4) THE STRUCTURAL SYSTEM OF THE SIX-PYLON CABLE-STAYED BRIDGE, (5) THE SOLUTION TO RELEASE TEMPERATURE LOADING FOR LONG BRIDGE DECK, (6) THE MAINTENANCE EQUIPMENT FOR MULTI-SPAN TWIN-DECK STEEL GIRDER, AND (7) THE CONSTRUCTION OF BRIDGE DECK. THESE STUDIES HAVE LED TO SIGNIFICANT ADVANCES IN UNDERSTANDING AND PREDICTING THE BEHAVIOUR AND THE CONSTRUCTION OF THOSE CABLE SUPPORTED BRIDGES WITH MULTIPLE SPANS.
