考虑地震影响的最优水泥混凝土路面研究
|
摘要
首先根据相似理论的分析计算得出了模型的相似系数,并且根据模型材料的选取原则确定了模型的材料类型,在此基础上设计了路基路面的物理模型。然后在研究地震对不同配合比以及不同配筋设计的水泥混凝土路面影响的基础上,通过比较不同配合比及不同配筋设计的模型在振动台上的破坏情况,找出几组抗震效果较好的模型,通过分析几组抗震效果较好模型的配合比及配筋设计,比较谁更经济合理。最终得出一种或几种实际抗震效果好,且经济适用的路面设计方案。
The physical model of road subgrade and pavement was firstly designed according to the analysis and calculation results of similarity theory and the selection result of materials.And then,based on the research on the effect of earthquake on the cement concrete pavements constructed according to different mixing proportions and reinforcement assembly designs,several group of models with relatively good earthquake resistance effect were obtained by comparing the destruction situation of models with different mixing proportions and reinforcement assembly designs on vibration table.Meanwhile,the mixing proportion and reinforcement assembly design of models with relatively good earthquake resistance effect are analyzed and compared,by which the economical efficiency and rationality of models can be determined.Finally,one or more pavement design schemes that have good actual earthquake resistance effect and are economical and practical were obtained.
