摘要
文章基于特征点弯沉等效原理,采用弹性层状体系和有限元方法,模拟刚性承载板的加载模式,以处治土路基顶面回弹模量满足规范要求为原则,引入公路重要性和施工变异性系数,给出了路基无机结合料处治深度的确定方法,并针对不同公路等级给出了路基处治深度的建议值。
Based on the deflection equivalence principle,the article uses the elastic multilayer theory and finite element method to stimulate load mode of rigid loading board.Also,the road importance and construction variability index are introduced with the requirement of modulus of resilience.The methods of determining the treatment depth of roadbed inorganic binding material is given in order to provide the suggestive treatment depth value for different road grade.
