【摘要】 在充分考虑碎石基层非线性 (弹塑性 )特性的基础上 ,采用非线性有限元法分析了吉林通化试验路 3种路面结构面层底面及半刚性基层底面弯拉应力的变化规律 ,并对通化试验路 2种具有碎石基层半刚性沥青混凝土路面结构的沥青混凝土面层的抗疲劳寿命进行了预估。更多还原

【Abstract】 On the basis of the non-linear(elasticity and plasticity) property of granular base, variation rules for maximum flexural tensile stress of surface course underside and semi-rigid base underside are studied with non-linear finite element solution for three types of pavements of a test road in Tonghua City of Jilin Province. Some reasonable suggestions are brought forward to semi-rigid asphalt concrete pavement with granular base in the test road. Fatigue lives of surfacing course of two types of semi-rigid asphalt concrete pavement with granular base are forcasted.更多还原
