摘　　要：基于弹性半空间地基模型,对公路飞机跑道水泥混凝土道面的基础弹性模量进行反算。通过静载下的实测弯沉、弹性半空间体理论弯沉以及Winkler地基理论弯沉的对比分析;并利用该反算结果,采用PCN来评价道面承载能力。通过某公路飞机跑道的实例,证明该方法较为方便,且精度较好,可以采用。Based on the theory of elastic half-space foundation,the Young＇s modulus of foundation of highway runway concrete pavement was back calculate,and give a comparative analysis between the measured deflections and theoretical calculated deflections which based on the theory of elastic half-space foundation and Winkler foundation under the static load. Then the bearing capacity of the pavement by PCN method was evaluated. An example of highway runway shows that this method is convenience and accurate enough,and can be applied to engineering practice.
