公路路桥设计及道路早期损坏原因分析

公路路桥设计及道路早期损坏原因分析公路路桥设计及道路早期损坏原因分析 摘要：路桥早期损坏现象在我国乃至国外都是一种多发、常见的病害，早期损坏对于路桥适用的安全性、稳定性、舒适度以及路桥的外观都有不利的影响。很多路桥工作者凭经验对早期损坏的起因和进展提出了很多看法和推测，并认为只有对早期损坏的真正原因了解透彻，才能使早期损坏的防治讨论有的放矢。本文从路桥损害的设计因素方面入手，就路桥过渡段不均匀沉降及桥面铺装剥离、坑槽、拥包等早期损害具体现象进行原因分析，并提出设计时应当注意的一些问题。 关键字：路桥设计；早期损坏；过渡段；桥面铺装 Abstract: luqiao early damage phenomenon in our country and abroad is a multiple, common diseases, early damage to luqiao applicable safety, stability, comfort and road and bridge appearance has adverse effects. A lot of road and bridge workers by experience for early damage causes and puts forward many ideas and theories, and holds that it is only the real cause of the early damage of thorough, to make early damage prevention research have a definite object in view. In this paper the design of bridge damage factors of road and bridge transition section of uneven settlement and bridge deck pavement stripping, potholes, smooches, bag and so on early damage phenomenon of specific analysis of the causes, and put forward the design should pay attention to some problems. Key words: road and bridge design; Early damage; Transition section; Bridge deck pavement 中图分类号： U448.14 文献标识码：A 文章编号：2095-2104（2025） 一、路桥过渡段不均匀沉降 （一）桥头引道软土地基设计未做合理的处理 软基路段由于地基沉降引起的桥头跳车现象普遍存在，这主要是由于：在施工图设计时，地质钻探布孔过少，钻探深度不够，未能及时发现软基存在，或者未能准确探明软基范围、深度等，导致桥头路堤软土地基处治遗漏，或是实行的处治方法不恰当。采纳的软基处治理论计算方法和选用的计算参数与软基实际情况存在一定差距，导致软基处治设计未能达到...
