Abstract

The invention provides a bridge and tunnel structure spanning 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 suspension bridge, and two ends of the main-tower-free suspension bridge are sequentially connected with the main line tunnels in the mountains on the two sides respectively. According to the bridge and tunnel structure, a suspension bridge main tower is omitted, the mountains are used for anchoring, 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 andhigh in practicability, and the problem that a suspension bridge crosses a canyon at an abrupt cliff is solved.

Description

technical field [0001] The invention relates to the technical field of bridges and tunnels, in particular to a bridge-tunnel structure across a canyon at a cliff and a construction method thereof. Background technique [0002] With the continuous development of my country's transportation, bridges and tunnel projects under various complex conditions are emerging. When the road needs to cross steep cliffs and canyons, the construction of bridges and tunnels is particularly difficult. Nowadays, long-span bridges such as suspension bridges are often used to cross the canyon. However, the construction of conventional suspension bridges generally requires the installation of a main tower. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bridge-tunnel structure and construction method for crossing canyons at steep cliffs, aiming to solve the problems of difficult site selection and difficult construction of the main ...
