Abstract

The invention discloses a model test system of an assembled double-tower ground-anchor suspension bridge. The system is composed of three parts: a test model of a double-tower ground-anchor suspension bridge, a moving load system and a data test system. The test model of the double-tower ground-anchored suspension bridge includes the main girder, the main tower, the main cable, the hanger, the support and the foundation. The sling is connected to the main beam through the adjusting nut, the lower part of the main beam is connected with the counterweight through the bolt, and the adjusting nut for adjusting the length of the main cable is installed at the anchorage position of the main cable. The mobile load system includes the vehicle model and weights, and the vehicle model is graded and refined according to the vehicle model and load class. This model test system contains three major test systems, including cable force, displacement and acceleration test systems. With the continuous construction of long-span suspension bridges in my country in recent years, the new prefabricated double-tower ground-anchor suspension bridge model test system will definitely provide many conveniences for bridge engineering research and technical personnel, so it has a wide range of engineering application prospects.

Description

technical field [0001] The invention relates to an assembled double-tower ground-anchor suspension bridge model test system, which is suitable for the field of bridge test science. Background technique [0002] The structure of the suspension bridge mainly includes main cables, suspension cables, bridge towers, anchorages and stiffening beams. Compared with other bridge types, the force is clearly defined, and it has the advantages of larger span, less material consumption and lower cost. Among the bridge types with a span of more than one kilometer, the suspension bridge with strong spanning capacity, lightness and beauty has increasingly become the preferred bridge type for long-span bridges. However, the structure of long-span suspension bridges is complex, and its nonlinear characteristics and local stress problems are relatively obvious. It is necessary to analyze various mechanical characteristics of its construction and operation stages through model tests, and to ver...
