PARTIALLY AND FULLY EARTH-ANCHORED CABLE-STAYED BRIDGE USING MAIN SPAN PRESTRESSING APPRATUS AND CONSTRUCTION METHOD FOR THE SAME

摘要

on the deck segments that are installed on the cable-stayed bridge with a main span tension means comprising a tension device and a tension member and the tensile stress introduced by the role of the conventional aerodynamic cable at the same time can be reduced to enable the cross sectional area of the main span of the deck segments by reducing the size of the maximum compression stress acting on the end face of the deck segments of the main span , cable-stayed bridge has been disclosed in accordance with this economically the compressive stress caused in whole or in part, it makes it possible to compensate for the main span tensile stress due to the tension member . ;
