重力式U型桥台病害及加固技术的应用

Gravity U-shaped Abutment Disease and Application of Reinforcing Technology

作为最为常见的一种桥台结构形式,重力式U型桥台在桥梁设计中应用较多,其主要通过自身的重力进行外力平衡。重力式U型桥台具有较为复杂的受力形式,特别是在自重力、汽车活载及土压力等作用下,极易产生病害,如桥台台身裂缝、基础不均匀裂缝等,这些病害的产生将对重力式U型桥台质量造成严重影响,为此必须重视桥台加固施工。本文在充分掌握重力式U型桥台病害机理的同时,提出了相应的加固方法,以期全面提升工程建设质量。

As the most common form of abutment structure, the gravity U-shaped abutment is widely used in the design of bridges. It mainly uses its own gravity to balance the external forces. Gravity U-shaped abutments have more complex forms of stress, especially under the influence of self-gravity, vehicle live load and earth pressure, it is easily to produce diseases, such as abutment bench cracks and uneven foundation cracks. These diseases will seriously affect the quality of gravity U-shaped abutments, so it is necessary to pay attention to the construction of abutment reinforcements. In this paper, while fully grasping the mechanism of gravity-type U-shaped abutment, a corresponding reinforcement method is proposed in order to fully improve the quality of project construction.
