连续配筋混凝土路面新型端部锚固结构研究
|
摘要
近年来,随着我国公路交通的快速发展,交通运输量不断增长,超载和重载车辆在整个交通流中所占的比例增加,高等级公路早期破坏现象日益严重,而连续配筋混凝土路面具有承载力强、耐久性好、行车舒适,能够在重载交通情况下,提供较好的路用性能,具有较高的实用价值。
本文以连续配筋混凝土路面端部制动板锚固系统为研究对象,从路面纵向位移与所需锚固力分析、有限元计算和试验路设计、施工、材料试验、现场观测等方面对新型端部制动板锚固系统进行了分析和研究。
首先,介绍了国内外对连续配筋混凝土路面纵向位移与所需端部锚固力的研究成果,推导了纵向位移和所需端部锚固力的计算公式,为端部制动板锚固系统设计研究提供了理论依据。
其次,研究了新型端部制动板锚固系统结构及工作机理,提出了端部制动板锚固系统设计方法,并得出了主要参数的影响规律。
再次,应用有限元软件计算了端部制动板锚固系统的位移与最大应力,将理论计算模型和有限元模型的计算结果进行了比较,提出了适合不同工程条件下制动板类型。
最后,依托贵州省贵阳市环城高速公路东绕线连续配筋混凝土路面改建工程,介绍了设计方案,结合试验路段进行材料试验和现场观测,并总结了端部制动板锚固系统施工工艺。
In recent years, with the rapid development of China's road transport,the growing volume of traffic and transport,overloading and overloading vehicles in entire transport stream proportion increase,high-grade highways growing phenomenon of the early damage. The CRCP has a strong bearing capacity and durability, driving comfort, able to heavy traffic conditions, the provision of better road performance, with a high practical value.
In this paper, continuously reinforced concrete pavement ends of brake plate anchorage system as research object, from Vertical displacement of road, analysis of the required anchoring force, analysis of the required anchoring force, test route design, materials Testing and Situ, a systematic research and analysis of the new type of brake plate end anchorage system.
Firstly, introduced at home and abroad continuously reinforced concrete pavement and the vertical displacement of the anchor force required to end the research results derived vertical displacement and the end of the anchor force required for the calculation formula for the braking plate end anchorage system design study has provided theoretical basis.
Secondly, researched a new type of brake plate end anchorage system and working mechanism of structural analysis of proposed brake plate end anchorage system design method, and obtained the main parameters were investigated.
Thirdly, application of finite element software to calculate the tip brake plate displacement and maximum stress, the theoretical calculation model and the finite element model results were compared for different projects proposed under the condition of brake plate type.
Finally, relying on highways around the city of Guiyang, Guizhou Province East Winding Road Continuously Reinforced Concrete Engineering, introduced the design, combined with test sections of material testing and field observations, and summarizes the brake plate end anchorage system construction process.
