Multi-tower high-low tower rigid frame system cable-stayed bridge structure
The invention provides a multi-tower high-low tower rigid frame system cable-stayed bridge structure which comprises a main beam, bridge piers, bridge towers and a plurality of stay cables with the two ends anchored to the bridge towers and the main beam respectively. The bridge piers comprise low piers arranged on the two sides in the bridge direction and fixedly connected with the main beam andhigh piers arranged in the middle in the bridge direction and fixedly connected with the main beam; each bridge tower comprises a side tower and a middle tower, the bottom of the side tower is fixedlyconnected with the main beam at the position corresponding to the low pier, the bottom of the middle tower is fixedly connected with the main beam at the position corresponding to the high pier, andthe tower height above the bridge surface of the middle tower is larger than that above the bridge surface of the side tower. The cable-stayed bridge structure adopts a bridge design scheme of combining the high-low towers and the high-low piers, the defect of large terrain height difference is overcome through combination of the high piers and the low piers, the terrain defect is changed into thebridge construction advantage, the bridge side span length is reduced, the bridge length and the number of the high piers are reduced, and the engineering cost is reduced; and after combination of staggered arrangement of the higher towers and low towers, the structure is more attractive.
本发明提供了一种多塔高低塔刚构体系斜拉桥结构，包括主梁、桥墩、桥塔以及两端分别锚固于桥塔和主梁上的多根斜拉索，所述桥墩包括设置在顺桥向两侧与主梁固结的低墩，以及设置在顺桥向中部与主梁固结的高墩；所述桥塔包括边塔和中塔，所述边塔底部与低墩对应处的主梁固结，所述中塔底部与高墩对应处的主梁固结，所述中塔桥面以上塔高大于边塔桥面以上塔高。该斜拉桥结构采用高低塔与高低墩结合的桥梁设计方案，通过高墩和低墩的结合不但解决了地形高差大的缺点，变地形缺点为建桥优势，缩减了桥梁边跨长度，减少了桥梁长度和高墩数量，降低了工程造价，同时结合高塔和低塔的错落布置，使得结构更具富有美感。
