Bridge and tunnel structure crossing canyon at abrupt cliff and construction method thereof
The invention provides a bridge and tunnel structure crossing a canyon at an abrupt cliff and a construction method thereof. The bridge and tunnel structure comprises main line tunnels, the main linetunnels are arranged in mountains on the two sides of the canyon, canyon sections of the main line tunnels are spanned by a main-tower-free cable-stayed bridge, and two ends of the main-tower-free cable-stayed bridge are sequentially connected with the main line tunnels in the mountains. According to the bridge and tunnel structure, a cable-stayed bridge main tower is omitted, anchoring is conducted through the mountains, the construction cost is low, and the landscape effect is good. Meanwhile, the construction method of the bridge and tunnel structure is low in difficulty and high in practicability, and the problem that a cable-stayed bridge crosses a canyon at a steep cliff is solved.
本发明提供了一种陡崖处跨峡谷的桥隧结构及其施工方法，其中，该桥隧结构包括主线隧道，主线隧道设置于峡谷两侧的山体内，主线隧道的峡谷段采用无主塔斜拉桥跨越，无主塔斜拉桥的两端分别顺接两侧山体内的所述主线隧道。本发明的桥隧结构取消了斜拉桥主塔，利用山体进行锚固，工程造价低、景观效果好。同时，该桥隧结构的施工方法难度小，可实施性高，解决了陡崖处斜拉桥跨越峡谷的难题。
