摘　　要：结合高等级公路工程实践，针对中国现行水泥混凝土路面设计规范中土基回弹模量建议值存在的不适应性，通过现场实测对比试验，建立了土基Ｅ０～ＢＭ的统计关系式，提出了中国自然区Ⅳ区土基回弹模量规范建议值的修正系数表，并提出了土基强度等级的划分。Based on the experiences of high grade highway construction and the unsuitable state existed in the recommended value for the earth subgrade rebound modulus regulated in the specifications for the design of cement concrete highway in China, a statistical equation E 0～B m for the earth subgrade is established by means of field survey and contrasting tests and a revised table of coefficient for the recommended value shown in specifications for the earth rebound modulus in the Ⅳ naturally divided regions in China is presented along with a division of the earth subgrade stength classification in this paper.
