一、山区桥梁的基础型式(一)山区桥梁的特点山区桥梁多在复杂的地形设置基础,与平原区相比,由于施工等各种困难而工程费用较大,故应尽可能设计成大跨径结构,以求减少基础个数,降低桥梁工程的造价。山区桥梁多在斜坡上设置基础,而山区地基的承载情况又很复杂,故在设计山区斜 First, the basic types of mountain bridges (a) the characteristics of mountain bridges Mountain bridges and more in the complex terrain to set the foundation, compared with the plain area, due to construction and other difficulties and the larger the project cost, it should be designed as large span Diameter structure, in order to reduce the number of basic and reduce the cost of bridge construction. Bridges in mountainous areas are often set up on the slopes, while the bearing capacity of mountainous areas is very complicated. Therefore, in the design of mountain slopes
