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, high-grade highways continue to extend to mountainous areas or complex terrain and geological conditions. The increasing number of bridge diseases caused by landslides has caused considerable losses and deserves the attention of relevant parties. Based on the research results of the rational cross-hole arrangement scheme of the middle and small-span bridges in debris flow, water damage and landslide area, this paper lists several types of bridge disease and studies the countermeasures based on the analysis of the causes of the disease, including the correct geological survey, reasonable choice Bridge position, bridge type and hole span arrangement and protective measures, etc. Meanwhile some successful treatment cases are introduced.
