摘要
空心板梁因其施工便利、造价低、建筑高度小等优势,在各类公路建设中运用较为广泛,尤其是在中小跨径桥梁工程中普遍采用。由于空心板梁的结构设计特点,在实际使用中较容易产生各种病害,这不仅给桥梁维修加固带来困难,也给公路的日常运营带来安全隐患。
Hollow slab beams are convenient to be constructed and they have advantages of low cost, low structural depth. So that it is widely used in various kinds of highway construction, especially in small and medium-sized span bridge engineering. As the structure design characteristics of hollow beam, it is inclined to create many kinds of diseases in the practice, which brings about not only some difficulties for bridge maintenance and reinforcement but also hidden safety hazard to highway normal operation.
