基于有效应力理论,推导了饱水状态下的沥青路面结构内部的孔隙水压力计算方程,并通过Matlab软件求得数值解,具体分析了孔隙水压力的变化规律以及标准胎压、混合料孔隙率和沥青材料弹性模量等材料参数变化对孔隙水压力产生的影响.
According to the principle of effective stress,this paper deduces the calculation equation on pore water pressure of internal asphalt pavement structure. Through the numerical solution obtained by the Matlab software,We analyzes the change law of pore water pressure and the impact of it by the standard tire pressure,porosity and elasticity modulus of asphalt mixture.
