| 摘 要： | 针对公路隧道水泥混凝土路面结构，建立了水泥混凝土路面结构的三维有限元分析模型.在考虑各种计算参数下采用了多元非线性回归方法，得出板纵向边缘中部底面拉应力和板角顶面拉应力的计算公式，并根据容许疲劳拉应力为设计指标提出公路隧道水泥混凝土路面设计方法，推导出水泥混凝土板厚计算公式.通过一个工程实例验证了该方法的有效性，为公路隧道水泥混凝土路面结构设计提供了理论依据. |

| Abstract: | A three-dimensional finite model of concrete pavement was established to suit for the concrete pavement in highway tunnel.A nonlinear regression method was used when considering the effect of structural factors.The calculating formula of the tensile stress on the bottom of the slab and the tensile stress on the slab surface was presented.Based on the admitted fatigue tensile stress as design index,the design mehtod of the concrete pavement in highway tunnel was concluded,and the calculating formula of slab thickness was also put foword.An engineering example was used to validate the method.It provides a theory base for the pavement design of the concrete pavement in highway tunnel. |
| Keywords: | highway tunnel cement concrete pavement finite element model hollow under the corner of slab design index |
