摘　　要：结合刚果(布)2号公路工程的现场承载板试验和贝克曼梁弯沉试验研究了压实度、稠度、弯沉值与土基回弹模量E0的变化规律,得出了土基回弹模量E0与稠度和压实度、土基回弹模量E0与弯沉的经验关系式,并将现场实测的土基回弹模量值与查表法得出的值进行了对比,在此基础上,提出了刚果(布)北部地区的土基回弹模量E0推荐值。We studied the variation of compaction, consistency ,deflection and subgrade resilient modulus E0 combined with Congo（cloth） on the 2nd Highway Engineering Field bearing plate test and Beckman Beam Deflection Experiment,obtained empirical relationships of subgrade resilient modulus E0 with the consistency and degree of compaction.subgrade resilient modulus E0 with the deflection, and compared the soil base resilience modulus values by field measurement with obtained by the look-up table method, on this basis, we proposed recommended values of subgrade resilient modulus Eo in Congo （cloth） in northern.
