| 摘 要： | 载荷试验是目前世界各国用以确定地基承载力的最主要方法，在地基处理效果检验中被广泛采用，然而载荷试验在实际操作过程中也存在不少问题，如尺寸效应、费用高、工期长等。新兴的有限元等数值方法克服了以往耗时量大、操作复杂、精度不足等缺点，已逐渐成为岩土工程领域有效的实用计算方法。鉴于上述原因，尝试用增量加载有限元法对载荷试验进行数值模拟。算例结果表明，只要强度参数与实际情况相符，载荷试验的结果可以通过有限元模拟获取。

| Abstract: | The Plate Loading Test is the most used way to acquired the bearing capacity of foundation in the world and it’s widely used in checking the results of the treatment foundation, but it also has some shortcomings, including size effects, high expense, time cost and so on. In this paper the FEM by step-loading was used to analyze the process of the Plate Loading Test and to obtain the bearing capacity of foundation. A lot of valuable results was got. |
