摘　　要：针对载荷试验结果不能反映地基基础的真实工作性状和荷载传递机理,同时,试验条件与地基基础的实际工作条件通常存在差异等问题,分析了载荷试验涉及的关键力学问题,进一步建立三维数值仿真模型,并与实际工程条件下的现场载荷试验结果比较。结果表明,数值仿真与载荷试验反映的荷载-沉降关系基本一致,验证了仿真模型的适用性。Loading test can not reveal the actual working behaviors and load transfer mechanism, and the testing condition is usually different from the actual working condition, therefore, the key mechanical theories involved in numerical simulation of loading test are studied, and the three-dimension numerical simulation model is founded. The suitability of the model is proved by comparing the real loading test results with the calculating results using the above model. The results indicate that the results of numerical simulation and loading test are basically similar.
