[0056] The main bridge of a certain bridge is a prestressed concrete cable-stayed bridge with five spans, two towers and two cable planes. The span of the main span is 360m. The standard section length of the main girder of the main bridge is 6m. , the design adopts a anchorage form of a corbelless steel anchor beam cable tower, such as figure 2 shown. The steel anchor beam of No. 3 main tower section No. 28 with the largest horizontal component force of the stay cables is selected, and Q345D steel is used. The maximum cable force of the stay cable J28 on the river side is 6146kN in the completed bridge state, and the maximum cable force of the stay cable A28 on the bank side is 6764kN, the stay cables are designed according to the asymmetric load. The middle span of the No. 28 section steel anchor beam is an open box section with an area of 86920mm 2 , the horizontal angles of stay cables J28 and A28 are 31.042 and 31.493 respectively, and the distance between anchor poi...
