当前公路工程建设实践中若干规范性问题研究

Study on Some Standardization Problems in Current Road Construction

结合对当前公路技术规范存在的一些疑问,提出了处理建议,具体包括对混凝土结构密实度控制和质量评定,公路弯道的横坡超高设计,对曲线段桥梁的精细化施工要求,是否设置挂篮悬浇箱梁桥面的混凝土调平层,桥梁预应力的有关设计和施工,承重支架和混凝土模板等施工临时结构有关问题,对公路桥梁的设计荷载标准与现实状况的比较分析,如何处理严格遵守现有规范和突破现有规范规定的矛盾。

Based on some questions in current road criterion, the author puts forward some treatment suggestions, including compactness control and quality evaluation of concrete structure, superelevation design of transverse slope for road bend, meticulous construction requirements of bridge for curve segment, leveling course of concrete for cantilever casting box girder bridge deck with setting hanging basket or no, related design and construction of prestress for bridge, related questions of temporary structure construction for bearing support and concrete formwork and so on,comparative analysis of design load standard and realistic condition for road bridge, how to treat the contradictions between keeping standard and breakthrough for standard.
