【摘要】 本文在分析了现有的水泥混疑土路面传荷系统模型不足的基础上,提出了传力杆支承在水泥混凝土弹性基础上的厚梁模型,在此模型中,传力杆接缝既可传递剪力又可传递弯矩。本文依.据该分析模型及有限元理论编制了相应的用于分析文克勒地基或弹性半空间地基上具有企口缝、假缝、平缝或传力杆接缝的水泥混凝土路面应力、位移及传荷能力的计算机程序(FEAJCP),此程序的正确性经与美国波特兰水泥协会的程序JSLAB的计算结果对比得到验证。本文的分析模型及相应的计算机程序可供路面设计理论研究参考。更多还原

【Abstract】 In this paper, the shortcomings of the present load-transfer models of concrete pavements are analyzed and a new analytical model which can transfer shear and moment through steel dowels is presented.The steel dowels are modeled as thick short beams resting on an elastic concrete medium. A computer program denoted as FEAJCP which is based on the new model and finite element theory is presented. It can analyse stresses, deflections and joint efficiencies of concrete pavements with keyed, aggregate interlock, flat or dowel joints. It has been proved correct compared with the results of the computer program named JSLAB of PCA. The model and the computer program may be used as a basis for theory research of concrete pavements designs.更多还原
