摘　　要：在对陕西省已建13条高速公路土基回弹模量调研的基础上,结合弹性层状理论计算分析,从经济技术考虑,提出其土基回弹模量最低为45 MPa,并将陕西省高速公路土基强度等级划为4个级别,为陕西省高速公路设计提供参考。Based on the investigation of the subgrade resilient modulus of the constructed 13 highways in Shanxi Province and combined with the calculation and analysis as per the theory of elastic layers, the subgrade resilient modulus of 45 MPa is proposed from the economic and technical viewpoint; the subgrade strength of highway in Shanxi Province is classified into 4 grades providing reference for the highway design thereof.
