提出了一种同时考虑空间变异性和统计不确定性的概率分析框架,以评估水泥土桩的整体强度。在这个框架中,统计不确定性评估样本数据使用贝叶斯推理。统计参数的推断是由马尔可夫链蒙特卡罗方法。在实现强度随机场时,采用参数的绘制值。然后,对生成的实现进行有限元分析。简要介绍了框架的组成部分,并进行了实例分析,以说明统计不确定性和空间变异性对评估的整体实力的影响。
A probabilistic analysis framework in which the spatial variability and the statistical uncertainty are considered simultaneously is presented to evaluate an overall strength of a cement-treated soil column. In this framework, the statistical uncertainty is evaluated from sample data using a Bayesian inference. The inference about the statistical parameters is performed by a Markov chain Monte Carlo method. The drawn values of the parameters are adopted when making random fields of strength as realizations. Then, the finite element analysis is conducted for the generated realizations. The framework components are briefly described, and an example analysis is performed to illustrate the influence of the statistical uncertainty and the spatial variability on the evaluation of the overall strength.
