提出了根据先验信息和较少的勘探数据确定土性参数标准值的贝叶斯框架,该框架对不同的土性参数、勘探数据和转换模型具有广泛的适用性.基于所提出的贝叶斯框架,采用Visual Basic for Applications(VBA)语言开发了岩土工程场地模拟及参数分析软件(WHUGSSPA),便于工程师应用.最后以砂土有效内摩擦角和标准贯人试验数据为例,利用软件确定的有效内摩擦角的均值和标准差与三轴压缩试验结果相差分别为0和0.1,说明所提方法的有效性和软件的实用性.
A Bayesian framework which applies widely to different soil properties, in-situ test data and transformation models is proposed to determine the standard values of soil properties according to test data and prior information. Based on the proposed Bayesian framework, this paper develops the geotechnical site simulation and parameter analysis (WHUGSSPA) using Visual Basic for applications, which is con- venient for engineers to use. At last, an example of the effective internal friction angle and standard pene- tration tests data is given to illustrate the availability of the proposed method and practicability of the soft- ware. And little difference (0 and 0.1 for mean and standard deviation) between the results from the soft- ware and triaxial compression test.
