Self-anchored suspension bridge with main cable ground anchors
The invention provides a self-anchored suspension bridge with main cable ground anchors, which comprises a main cable, cable bent towers, stiffening beams, slings and side piers, wherein the cable bent towers are positioned on two sides or in the middle of the bridge surface; a main cable saddle supporting main cable is arranged at the top of the cable bent tower; cable rotating saddles are arranged at the two ends of the stiffening beams; the main cable bypasses the rotating cable saddle at the end part of the stiffening beam and then is vertically and downwards anchored on the foundation ofthe side pier; the anchoring section, below the cable rotating saddle, of the main cable comprises a whole cable section and a scattered cable section, a scattered cable sleeve is arranged between thewhole cable section and the scattered cable section and provided with a fixed support in the bridge direction, the slings are evenly arranged between the main cable and the stiffening beam, the sidepiers are located below the ends of the stiffening beam, and supports are arranged at the tops of the side piers to support the stiffening beam. According to the self-anchored suspension bridge withthe main cable ground anchors, the main cable bypasses the cable rotatingsaddle at the end part of the stiffening beam and then is vertically and downwards anchored on the foundation of the side pier, so that the structure of an anchoring area of the main cable at the beam end can be greatly simplified, and the anchoring and maintenance of the main cable are facilitated.
本发明提供一种主缆地锚的自锚式悬索桥，包括主缆、索塔、加劲梁、吊索和边墩，所述索塔位于桥面两侧或中间，索塔顶部设主索鞍支撑主缆，所述加劲梁的两端设有转索鞍，所述主缆在加劲梁的端部绕过转索鞍后铅垂向下锚固在边墩的基础上，所述主缆在转索鞍下方的锚固段包括整缆段和散索段，两段之间设有散索套，所述散索套设有顺桥向的固定支撑，所述吊索均匀布置在主缆和加劲梁之间，所述边墩位于加劲梁端部的下方，边墩顶部设支座支撑加劲梁。本发明提供一种主缆地锚的自锚式悬索桥，将主缆在加劲梁端部绕过转索鞍后铅垂向下锚固在边墩的基础上，可以大大简化梁端主缆锚固区的构造，方便主缆的锚固和养护。
