A seagull-style space back-cable cable-stayed bridge system

Abstract

This application relates to a seagull type space cable-stayed bridge system, including bridge towers, cable-stayed cables, main girders, side piers, middle piers, back cables and cables, and relates to the technical field of bridge engineering, wherein the bridge towers are designed as Arc-shaped, the two ends of the back cable are anchored to the top of the bridge tower respectively, and one end of the cable is connected to the back cable, and the other end is anchored to the root of the bridge tower, so that the bridge tower, back cable and cable form a three-dimensional frame structure, which can be Improving the spatial stiffness of the cable-stayed bridge is beneficial to resist the effects of dead load and live load, and the back cable can be stretched at the top of the tower to adjust the cable force, and the stay cable can be stretched at the root of the bridge tower to adjust the cable force. In order to improve the stress state of the bridge tower under the action of its own weight and the tension of the stay cables, the line shape of the bridge tower is close to the reasonable arch axis, and the bending moment on the root of the bridge tower is reduced, that is, there is no need to change the cross-section of the tower bottom The size is designed to be very large, so the application can not only enhance the spanning capacity of the cable-stayed bridge, reduce material loss and cost, but also enhance the aesthetic feeling of the bridge.

Description

Technical field [0001] The present application relates to the field of bridge engineering, and in particular, there is a seagull space to resemble the cable-laid bridge system. Background technique [0002] The cable-stayed bridge is a bridge structure consisting of bridge towers, main beams and transers, usually divided into a double tower cable-laundry bridge, a Tacted Cable Bridge, a palerous bridge, and an endless cable-free bridge. The cablewide bridge has a towering bridge tower, giving a strong visual impact; relatively slender main beams, the strong strength of the slope; the flexible cable and structural arrangement gives designers vast imagination Thus, there is a large number of urban landscape bridges. [0003] With the advancement of society and the development of urban construction, the city bridge is no longer a powerful shunt of transportation, but the trend of practicality and beauty, and the bridge design of the economy and the aesthetics is very important.
