基于分层贝叶斯学习的滨海软土地层高效识别方法
Efficient Identification Method of Coastal Soft Soil Stratum Based on Hierarchical Bayesian Learning
,
基于静力触探试验数据划分土层依赖于经验图表和主观判断,划分的土层剖面不可避免地存在不确定性.提出了一种基于土体分类指数Ic 的土层界面快速识别和不确定性量化方法.在分层贝叶斯学习框架下,所提方法采用全高斯概率模型表征土体空间变异性,通过引入正态‒逆威沙特共轭分布实现似然函数的快速计算,高效求解模型证据,识别最可能土层数目和厚度.所提方法基于Ic 的统计特性自动划分土层,提高了识别结果的可靠性.
