摘要
近年来高等级公路不断向山区或复杂地形、地质条件地区延伸,滑坡引起的桥梁病害日渐增多,造成不小的损失,值得有关方面重视。文章根据山区泥石流、水毁、滑坡地区中小跨径桥梁合理孔跨布置方案的研究成果,列举了若干桥梁病害型式,在分析病害原因的基础上,研究对策,包括正确的地勘判断、合理选择桥位、桥型和孔跨布置以及防护措施等,同时介绍了一些成功处治的案例。
In recent years the first-class highway has extended unceasingly to the mountainous area or the complex terrain, and the landslide caused bridge damages more and more. It has brought us losses and aroused the local government＇s concern. According to the research results on the reasonable cross hole scheme of small span bridges in mountainous area, the article has enumerated some bridges damage pattern, and on the analysis of damage reason put forward some research countermeasures, including the correct place, the reasonable choice of bridge site, bridge model and the hole cross arrangement as well as the protective measure and so on, simultaneously introduced some successful disposal cases.
