摘　　要：在工程勘察中,地基土承载力是勘察所需要得到的重要参数之一,为后续的设计工作提供最为重要的参考依据。介绍了地基土承载力确定的几种常用方法,比较了各种方法的适用范围、优缺点。同时结合实际的工程,利用不同的方法确定同一区域的地基土承载力,分析了所确定的地基土承载力存在差异的原因;对同一种方法在相同区域、不同的条件下确定的地基土承载力存在的变化和差异进行了研究,为类似的工程提供了一些参考。The bearing capacity of foundation soil is one of the key parameters of civil investigation project and provides signifi cant reference for the subsequent design work. The paper intro duced several general approaches to determine the bearing capaci ty of foundation soil, and compared their application scope, strength and weakness. Besides, using the actual project as a sample, the paper analyzed the causes of capacities differences calculated by different approaches in same area, and studied the varieties and differences calculated by same approach in same are a under different circumstances, providing references for similar projects.
