摘要 为了更准确评价边坡稳定性, 提出了岩土域的概念, 定义为处于同一地域、具有内在联系的多个岩土体构成的系统。构建了一个耦联分析概念性模型, 包括数据层(输入层和响应层)和分析层(模型层和计算层)这2大类。模型以数据驱动为主。数据是模型的核心和基础, 其来源不再是统一格式的, 而且是开放的, 可以接受分析层提供的数据以及其他来源的信息。各岩土体的模型和响应是彼此独立的, 其相互耦联通过输入层和计算层实现, 通过利用其他岩土体数据提高特定岩土体的分析精度。采用岩土域耦联分析理论分析了某库区边坡群的稳定性, 分析结果表明水位变化对边坡稳定性影响显著。

Abstract:A geo-domain concept was developed to more accurately evaluate slope stability. The geo-domain was defined as a system consisting of a few geo-bodies located in a region with internal relationships. A coupling model was developed with a dada layer (input layer and response layer) and an analysis layer (model layer and computation layer). The model is driven by the data as the core. The dada input does not have to have a unified format and is related to the analysis layer and other sources. The geo-body model and response are independent of each other. The coupling of the geo-bodies is captured by the input layer and the computation layer. Thus, the geo-body analysis can be improved by using data from other geo-bodies in the geo-domain. The stability of slopes near a reservoir was analyzed using the coupling analysis theory of the geo-domain. The results show that the slope stability is significantly influenced by water level changes.
