The invention discloses a carbon fiber composite inhaul cable oversized span part suspension hybrid cable-stayed bridge. The cable-stayed bridge comprises a main beam, an oversized span part suspension part and an oversized A first bridge tower and a second bridge tower; a first cable saddle and a second cable saddle; a first anchor and a second anchor; at least one part of the first back cable is made of a carbon fiber composite material, the lower end of the first back cable is connected with the first anchorage, at least one part of the second back cable is made of a carbon fiber composite material, and the lower end of the second back cable is connected with the second anchorage; the plurality of first inhaul cables comprise at least one first cable-stayed suspension cable and at least one first cable-stayed cable, the plurality of second inhaul cables comprise at least one second cable-stayed suspension cable and at least one second cable-stayed cable, and the first cable-stayed suspension cables and the second cable-stayed suspension cables are carbon fiber composite material inhaul cables; the upper end of the first cable-stayed suspension cable is connected with the upper end of the first back cable, the joint is supported on the first cable saddle, the upper end of the second cable-stayed suspension cable is connected with the upper end of the second back cable, the joint is supported on the second cable saddle, the upper end of the first cable-stayed suspension cable is connected with the first bridge tower, and the upper end of the second cable-stayed suspension cable is connected with the second bridge tower; the two ends of the horizontal cable are connected with the lower end of at least one of the first inhaul cables and the lower end of at least one of the second inhaul cables respectively; the lower ends, connected with the horizontal cable, of the first inhaul cables and the second inhaul cables are connected with the main beam through the slings. The oversized span partially-suspended hybrid cable-stayed bridge with the carbon fiber composite inhaul cables has the advantages of being low in cost, convenient to control the height of the bridge tower, large in span, low in cable shearing resistance requirement and the like.
本发明公开了一种碳纤维复合材料拉索超大跨径部分悬吊混合斜拉桥，包括：主梁；第一桥塔和第二桥塔；第一索鞍和第二索鞍；第一锚碇和第二锚碇；第一背索和第二背索，第一背索的至少一部分为碳纤维复合材料，第一背索的下端与第一锚碇相连，第二背索的至少一部分为碳纤维复合材料，第二背索的下端与第二锚碇相连；多个第一拉索和多个第二拉索，多个第一拉索包括至少一个第一斜拉悬索和至少一个第一斜拉索，多个第二拉索包括至少一个第二斜拉悬索和至少一个第二斜拉索，第一斜拉悬索和第二斜拉悬索均为碳纤维复合材料拉索，第一斜拉悬索的上端与第一背索的上端相连且连接处支撑在第一索鞍上，第二斜拉悬索的上端与第二背索的上端相连且连接处支撑在第二索鞍上，第一斜拉索的上端与第一桥塔相连，第二斜拉索的上端与第二桥塔相连；水平索，水平索的两端分别与多个第一拉索中的至少一个的下端和多个第二拉索中的至少一个的下端相连；吊索，多个第一拉索和多个第二拉索中与水平索相连的下端通过吊索与主梁相连。根据本发明实施例的碳纤维复合材料拉索超大跨径部分悬吊混合斜拉桥具有成本低、便于控制桥塔高度、跨径大、缆索抗剪要求低等优点。
