Abstract

The invention provides a half-through suspender-free tie-rod-free thrust-free continuous arch bridge structure system. The half-through suspender-free tie-rod-free thrust-free continuous arch bridge structure system comprises a foundation, a main pier, a main arch rib, an inverted arch and a main beam. The main pier is built at the top of the foundation, the main arch rib is arranged at the top of the main pier, the main arch rib and the main beam are fixedly connected at an intersection, the main arch rib is provided with the inverted arch, and the inverted arch and the main beam are fixedly connected at the intersection. The half-through suspender-free tie-rod-free thrust-free continuous arch bridge structure system is free of suspenders and horizontal tie rods, has the common advantages of a continuous beam bridge and an arch bridge, not only solves the limitation that the span of the continuous beam bridge is limited, but also avoids the influence of adverse factors such as complex arch bridge construction process, high construction cost and high management and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a continuous arch bridge structure system without suspenders, tie rods, and thrust. Background technique [0002] At present, a part of the main girder of the intermediate arch bridge structure system is suspended under the arch rib through suspenders, and the other part of the main girder is supported on the arch rib by columns. The existing half-supported arch bridge system has a large self-weight and a corresponding horizontal thrust, which not only increases the engineering quantity of the substructure, but also has higher requirements for the foundation. [0003] Due to the large horizontal thrust of the arch bridge, in the continuous multi-hole bridge, in order to prevent the safety of the whole bridge from being damaged due to the damage of one of the holes, it is necessary to adopt more complicated measures or set up a one-way thrust pier, thereby increasing the...
