本文通过对广东省有代表性的高等级公路路基承载板测试数据分析，建立了土基回弹模量（E0）同土基回弹弯沉（l0）的关系式，并同湖南省某公路同土质路基承载板测试结果进行了对比。统计分析表明，二者无显著差异。最后通过合并整理，建立了可供路基施工控制应用的E0与l0经验关系，并同规范推荐公式进行了比较。
Based on the analysis of test data of subgrade bearing plate of representative high grade highway in Guangdong Province, this paper establishes the relationship between the modulus of rebound (E0) of soil subgrade and the rebound deflection (l0) of soil subgrade, The test results with soil subgrade bearing plate are compared. Statistical analysis showed that there was no significant difference between the two. Finally, through consolidation, the empirical relationship between E0 and l0 for subgrade construction control application was established and compared with the standard recommended formula.
