摘要
通过对河北北部山区通村公路进行现场试验,由回归分析得到土基回弹模量与弯沉的关系式,并根据不同土基强度与不同标准轴载对路面厚度设计的影响,对土基强度进行分级,可作为路面设计的依据。
Through site experiment on the mountain area country roads in the north of Hebei Province,the relational expression between soil modulus of resilience and flexure is obtained through regression analysis.According to the effects of different soil base′s intensity and standard axle load on the road thickness design,the soil base′s intensity is classified to be the basis of the road surface design.
