| 摘 要： | 文章通过建立不设基层的隧道水泥混凝土路面的分析模型,运用三维有限元分析方法,对隧道路面不设基层时在不同基岩模量和轴载下的弯拉应力进行分析,判断在何种基岩模量下可以不用铺筑基层而能保持水泥混凝土板不出现弯拉强度不足的情况。从而可以充分利用基岩的高强度,减薄路面总的厚度,节省造价。

| Abstract: | Based on the analytical model of cement concrete pavements in tunnel section that has no base course,the paper,by means of tridimensional finite element analysis method,analyzes the bending force and tensile stress of the captioned tunnel pavement under different bedrock modulus and axle load.With the analysis,the paper also judges what kind of bedrock modulus can maintain adequate tensile strength in the cement concrete slab that has no base course.The paper concludes that the high strength of bedrock shall be brought to its full play so as to reduce the total thickness of pavement and thus save cost. |
