摘　　要：利用试验对比的方法,将标准贯入试验结果与桂林市红粘土地基承载力结果(平板载荷试验)进行比较,从试验原理、不同深度下的土压力差异以及钻杆因素3个方面来分析产生承载力差异的原因,讨论了造成标准贯入试验差异的因素。Through test and comparison, this paper compared the results of the standard penetration test with the bearing capacity of red clay foundation （through plate loading test） in Guilin. The authors analyzed the causes of the difference in bearing capacity from three aspects： experimental principles,soil pressure difference at different depths and drill rod factors. At last, the authors discussed the factors that led to the difference of standard penetration tests.

关 键 词：标准贯入试验 平板载荷试验 地基承载力 桂林市红粘土
