摘要
为了系统分析路基模量对路面结构受力状态的影响规律,建立了移动载荷作用下路面结构动力响应的力学分析模型,发现随着土基模量的增加,路面结构的动力响应提前,路面结构层内的应力及路面结构层间剪应力均有变化,但变化规律不一。研究结果对于路面设计及路基施工质量控制具有一定的参考意义。
For systematic analysis of the influence of the subgrade modulus of pavement structure bearing state law,established the dynamic response of pavement structure under moving load mechanics analysis model,it is found that with increasing modulus of soil base and pavement structure dynamic response in advance,within the pavement structure layer stress and shear stress between pavement structure layer all have change,but change rule.The research results have certain reference significance for pavement design and subgrade construction quality control.
